 Exhibit 4.1 

Execution Version 

Registration Rights Agreement Memorandum of Understanding 

This Registration Rights Agreement Memorandum of Understanding (this “MOU”), dated as of September 21, 2014, is entered
into by and among (i) TTM Technologies, Inc., a Delaware corporation (together with any successor entity thereto, “Parent”), (ii) Hicks, Muse, Tate & Furst Equity Fund III, L.P., HM3 Coinvestors, L.P., HMTF Equity
Fund IV (1999), L.P., HMTF Private Equity Fund IV (1999), L.P., Hicks, Muse PG-IV (1999), C.V., HM 4-P (1999) Coinvestors, L.P. and HM 4-EQ (1999) Coinvestors, L.P. (together, the “HM Funds”), and (iii) GSC Recovery
II, L.P. and GSC Recovery IIA, L.P. (together, the “BD Funds”). Each of Parent, the HM Funds and the BD Funds are sometimes referred to herein as a “Party” and collectively as the “Parties.” 

Reference is hereby made to that certain Registration Rights Agreement, dated as of April 9, 2010, (the “Tang
Agreement”) by and among Parent, Su Sih (BVI) Limited (“SSL”) and Tang Hsiang Chien (collectively with SSL, the “Tangs”). Capitalized terms used and not otherwise defined herein shall have the respective
meaning ascribed to them in the Tang Agreement. 
  

	1.	Registration Rights Agreements 

 Prior to the Closing (as defined in that certain
Agreement and Plan of Merger, of even date herewith, among Viasystems Group, Inc., a Delaware corporation, Parent, and Vector Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Parent (the “Merger Agreement”)),
the Parties will enter into a registration rights agreement, substantially in the form of the Tang Agreement with such changes and modifications as contemplated by Sections 2, 3, 4 and 5 herein and such other reasonable changes and modifications as
the Parties may mutually agree (including such changes as appropriate to reflect the structure of the HM Funds and the BD Funds) (such execution version of the registration rights agreement, the “Final Agreement”); provided that for
the HM Funds and the BD Funds, the definition of “Registrable Securities” in the Final Agreement will not include clauses (ii), (iii) and (iv) of the second sentence of that definition in the Tang Agreement. 

 

	2.	HM/BD Priority Period. The Final Agreement shall provide for a priority period of 90 days commencing when Parent files its required Form 8-K regarding consummation of the Merger (as defined in the Merger
Agreement) that includes required historical and pro forma financial statements (such period, the “HM/BD Priority Period”). During the HM/BD Priority Period and, if the HM Funds or the BD Funds have exercised the demand registration
right contemplated by Section 2(a) below, following the HM/BD Priority Period until the completion of such offering: 

  

	 	(a)	Each of the HM Funds and the BD Funds shall be entitled to exercise a single demand registration right for their resale of shares, including in an underwritten public offering that Parent will support (including through
participation of the CEO and CFO in road shows); 

  

	 	(b)	Each of the Tangs (on behalf of itself and its affiliates, transferees, successors and assigns) has agreed not to make a registration demand, and Parent shall not permit the exercise by the Tangs of a registration
demand; 

  

	 	(c)	Parent shall otherwise provide for “clear markets”; and 

  

	 	(d)	The Tangs (as well as the HM Funds and the BD Funds) will have piggyback registration rights relating to any demand by the HM Funds or the BD Funds. If the underwriters limit the number of shares that may be included
for any reason and the Tangs have exercised their piggyback registration rights, then each of the Tangs, the HM Funds and the BD Funds will be cut back in proportion to their ownership. 









	3.	Subsequent to the HM/BD Priority Period. Following the HM/BD Priority Period: 

  

	 	(a)	For a period of 2 years after the conclusion of the HM/BD Priority Period, each of the HM Funds and the BD Funds shall continue to have its single demand registration right unless exercised during the HM/BD Priority
Period; 

  

	 	(b)	If the HM Funds or the BD Funds are cut back pursuant to Section 2(d) above, then for a period of 2 years after the conclusion of the HM/BD Priority Period each of the HM Funds and the BD Funds shall be entitled to
one additional demand registration right; 

  

	 	(c)	For a period of 2 years after the conclusion of the HM/BD Priority Period, the HM Funds and the BD Funds will be entitled to exercise piggyback registration rights, including with respect to underwritten offerings
initiated by Parent or the Tangs; 

  

	 	(d)	If the underwriters limit the number of shares that may be included in any underwritten offering of Parent shares pursuant to a registration demand by the HM Funds or the BD Funds, (i) the Tangs will be cut back
before any required reduction of shares to be registered by the HM Funds or the BD Funds, and (ii) any required cut back of the HM Funds or the BD Funds will be proportional to their ownership; and 


 

	 	(e)	If the underwriters limit the number of shares that may be included in any underwritten offering of Parent shares pursuant to a registration demand by the Tangs or the Parent, the HM Funds and the BD Funds will be cut
back first (in proportion to their ownership) before any required reduction of shares to be registered by the Tangs. 

  

	4.	Expenses 

 Parent shall bear and pay all registration expenses (including road show
expenses) related to the exercise of rights under the Final Agreement, except that each of the HM Funds and the BD Funds shall bear and pay (a) all fees and expenses of its respective legal counsel or other advisors and its other respective
out-of-pocket expenses, (b) underwriting discounts and brokerage commissions attributable to the sale of their respective shares, and (c) commissions, fees, discounts, transfer taxes or stamp duties and expenses of any underwriter or
placement agent applicable to their respective shares. 
  

	5.	Holdback Period. 

 During the Holdback Period, any of the HM Funds or the BD Funds will
not be permitted to transfer shares to the limited or general partners or members of such HM Funds or BD Funds. 
  

	6.	Miscellaneous 

  

	 	(a)	Termination. This MOU shall survive the Closing. Unless the Closing occurs, this MOU shall terminate automatically (i) as to the HM Funds, upon the termination of that certain Voting Agreement, of even date
herewith, by and among Parent and the HM Funds (the “HM Voting Agreement”), (ii) as to the BD Funds, upon termination of that certain Voting Agreement, of even date herewith, by and among the Parent and the BD Funds (the
“BD Voting Agreement”), and (iii) in its entirety upon the termination of both the HM Voting Agreement and the BD Voting Agreement. 

  

	 	(b)	 Specific Performance. Each Party hereto acknowledges that it will be impossible to measure in money the damage to the other Parties if a Party
hereto fails to comply with any of the obligations imposed by this MOU, that every such obligation is material and that, in the event of any such failure, the other Parties will not have an adequate remedy at law or damages. Accordingly, each Party
hereto agrees that injunctive relief or other equitable remedy, in addition to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose the seeking of such relief on the basis that the other Parties have an











	 	
adequate remedy at law. Each Party hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with another Party’s seeking
or obtaining such equitable relief. 

  

	 	(c)	Entire Agreement. This MOU supersedes all prior agreements, written or oral, among the Parties hereto with respect to the subject matter hereof and contains the entire agreement among the Parties with respect to
the subject matter hereof. This MOU may not be amended or supplemented, and no provisions hereof may be modified or waived, except by an instrument in writing signed by all of the Parties hereto. No waiver of any provisions hereof by any Party shall
be deemed a waiver of any other provisions hereof by such Party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such Party. 

  

	 	(d)	Notices. All notices, requests, claims, demands, and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of
receipt), (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested), (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal
business hours of the recipient, and on the next business day if sent after normal business hours of the recipient, or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid. Such
communications must be sent to the respective Parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 6(d)):

	 	(e)	Governing Law. 

  

	 	(i)	This MOU shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any
other jurisdiction) that would cause the application of Laws of any jurisdiction other than those of the State of Delaware. 

  

	 	(ii)	All actions arising out of or relating to this MOU shall be heard and determined in the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the State of Delaware declines to accept
jurisdiction over a particular matter, any federal court within the State of Delaware). The Parties hereby (i) submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, only if the Court of Chancery of the
State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware) for the purpose of any action arising out of or relating to this MOU brought by any party and (ii) irrevocably waive,
and agree not to assert by way of motion, defense, or otherwise, in any such action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that
any such action is brought in an inconvenient forum, that the venue of such action is improper, or that this MOU or the Transactions may not be enforced in or by any of the above-named courts. Each of the Parties hereto agrees that mailing of
process or other papers in connection with any action or proceeding in the manner provided in Section 6(d) or such other manner as may be permitted by law shall be valid and sufficient service of process. 


 

	 	(iii)	 EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS MOU IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND,
THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS MOU. EACH PARTY TO THIS MOU CERTIFIES AND ACKNOWLEDGES THAT (A) NO
REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR 










	 	
OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS MOU BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6(e)(iii). 


 

	 	(f)	Enforceability. If any term or provision of this MOU is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this
MOU or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the Parties shall negotiate in good faith to modify this MOU
so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner. 

  

	 	(g)	Counterparts. This MOU may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. 


 

	 	(h)	Further Assurances. The Parties shall execute such further documents and take such further actions as may be reasonably necessary to implement and carry out the intent of this MOU. 


 

	 	(i)	Headings. All section headings herein are for convenience of reference only and are not part of this MOU, and no construction or reference shall be derived therefrom. 


 

	 	(j)	No Assignment. No party to this MOU may assign any of its rights or obligations under this MOU without the prior written consent of the other Parties. Any assignment contrary to the provisions of this
Section 6(j) shall be null and void. 

  

	 	(k)	Third Parties. Notwithstanding anything contained in this MOU to the contrary, nothing in this MOU, expressed or implied, is intended to confer on any person (other than the successors and permitted assigns of
the Parties) any rights, remedies, obligations or liabilities under or by reason of this MOU. 

  

	 	(l)	Several Obligations. The rights and obligations of each of the Parties under this MOU shall be several and not joint. All references to actions to be taken by the Parties under this MOU refer to actions to be
