Hey on your 2014-15 rear bumper/tail light conversion where did you get your harness at? My 2010 Camaro SS has rear backup sensors and so does my 14 ZL1 rear bumper. Taillights I went with Morimoto led tail lights but plug and play for the 14-15 Camaro.
Yes i did. That's where the major modification came in. I had to open the hole on the housing a little at a time until the projector cleared the front lens. Then I used a big washer from a front strut (yes the front camaro strut has a big washer under the nut that holds the spring to the strut) that will go over the projector back housing and made some clamps that held the projector tight against the rear housing.
I'm trying to do the same thing you have with the quad headlights with halo's and demon eyes on the 2014 Camaro, but I have run into an issue with one of the projectors hitting the plastic clear cover, did you have this issue as well and if so how did you fix it?
