Sorry ...bought an 09 broken headlight to transplant into my 05 headlight case. No this ism nor a plug and play transfer. A wire was pulled out of the solenoid that operates the hi/ low beam. Found a replacement and with a couple of minor mods it fit. Was not successful in removing the outer lens but stopped short of deforming it. Had to cut the back out with great care and with a bit of enginuity and a few mods all the 09 gear was installed. All functions work and all the afs codes from direct wiring the 05 (5pin) into.the 10 pin chassis plug have corrected. The hen 1 headlight cost me $200 some years ago and the broken 09 was $50 so $250 and some time( about 10 hours) on the bench has my baby happy again at a lot less than available price now. I was told it could not be done. If we want to keep them on the road we have to work outside the box and li es that limit us. Remember! The real enemy and villain in all this is GM . If they don't want to support them that is fine but stop giving us, the owners, the middle finger and let the specks loose so aftermarket replacements can be made. Shame on all of you at GM.....please feel free to kiss where I can't. For the forum. Don't take no for an answer. I have replaced the burned out led's in a taillight and modified this headlight so never give up you can fi d a way to do it if you try.
