content: I am making custom light accessories for my car because some of the incandescent bulbs are going dim and I can't find the LED versions in warm white to look like the old incandescent bulbs.I plan to use these components I found on AliExpress (see list) as donor housings for my custom PCBs and I couldn't manage to find what connector types / dimensions the circled ones are. This is so that I can know ahead of time if it is possible to get away doing a plain wire out, for both the PCB and possible alternative housing, to crimp on a possible male connector because I don't want to snip the car's wiring harness.Alternatively, I could probably just replace the natural white LEDs with warm white LEDs of the same footprint and similar voltage drop but I really want an excuse to work with Al PCBs for once.Also I know that I can replace the bulbs with T5s and CxW-y mm bulbs but I have a strong history of applying too much force pushing in and breaking the-manufacturer-didn't-put-enough-plasticizer-to-make-it-soft polycarbonate snap-in clips.Attached Image DescriptionImage 1: License Plate light (Manufacturer Part No. 63267165646, 63267193293) base image fromhttps://www.aliexpress.us/item/3256803792076310.htmlImage 2: Courtesy light (Manufacturer Part No. 63316972605, 63316961999, 63316902911, 63316962009) base image fromhttps://www.aliexpress.us/item/3256807387011538.htmlImage 3: Trunk light (Manufatruer Part No. 63316962039) base image fromhttps://www.aliexpress.us/item/3256807264964446.htmlHere is an image that is a better representation ofImage 2I found on eBay:https://i.ebayimg.com/images/g/C~sAAOSwWp1lTaTQ/s-l1600.webp

content: Edit: Sorry. It seems to be Tyco MQS.By the way BMW like to use connectors that are produced only for them and are hard to officially buy without their approval.

content: They look to me like they take MQS connectors from TE / AMP Germany, perhaps even one of the attached. For those, each color has a different key – which you can usually snip off if you have the wrong color for the device.

content: Quote from: jfiresto on September 13, 2024, 07:40:00 amYes. But I think all the major distributors have them.Just remember that some list them by the abbreviation MQS, others by the full name, Micro Quadlok. (MQS = Micro Quadlok System)

content: Hey,Quote from: DavidKo on September 13, 2024, 06:57:04 amThank you all for responding!It really helped with my search; and right now I am designing the PCB and housings to have 2-pairs of wire out with waterproof gaskets. The plan is to crimp the male connector on the two wire output. I also managed to figure out that 2a, thanks to the image @jfiresto provided:Quote from: jfiresto on September 13, 2024, 07:35:22 amI also bought a few connector pairs to test out the housing parts to double check if they fit.So in summary,1.a) unknown1.b) as @jfiresto says, I will try snipping one side of2.aoff2.a) 1-1718333-13.a) likely 9-968554-1 (possibly jfiresto compatible with 968699?), e.g.https://www.amazon.com/2-Pin-Connector-compatible-9-968554-1/dp/B0D6QTB83PQuote from: tooki on September 13, 2024, 11:14:08 amLol, I think I also found the air sensor / turn light side indicator / general waterproof connectors with the search term you provided:https://www.corsa-technic.com/item.php?item_id=1693&category_id=357I'll post an update as soon as I get the connectors and am able to test the fit.I also have an additional question that I created on another thread. It is about putting a power resistor in parallel to avoid CAN bus errors. The gist of the question is because I am switching from incandescent (stock) bulbs to LEDs, whether or not a vehicle's CAN bus system will throw or generate errors if the current draw for a system is too low. So the solution would be to put a power resistor in parallel to increase the current draw.
