Product review (4 stars): Works fine without the sleeve
The entire install can be done in 45 minutes if you do not try to reinstall the plastic sleeve.  Works fine without the sleeve........or spend 4 hours trying to get the sleeve on (like I did with the first one) and crimp the heck out of the wire as you get towards the bottom of the wire. This was my second try. I had to throw the first one away because I crimped the wire trying to get the sleeve on.
