Hello all, new member here. I have an '04 Deville
 

with the 4.6L Northstar. Strange one that is. My main problem is that the LR window wouldnt roll down. We went out to the salvage yard looking for a motor/regulator that might work considering what little we paid it was no prob to grab 2 of which neither worked. It wasnt hurting my feelings to bad so this got put to the side. Well, that same trip to said salvage, we found a pristine Bose system and the speakers look brand new. Put in the 2 rear door speakers first (considering we had the door panels off from previous adventure. Anyway the 2 I have installed sound great so I took out the original 12 inch in the back deck and have still failed to get it to work. After that whole story you know all I really want is a wiring diagram for the amp and stereo system which I cant seem to find. I couldnt find it in my Chiltons. I have also since decided to start metering everything, I dont really know how far this goes. So any assistance with wiring diagrams or tricks of the trade for a bose swap-out would be so very appreciated. I have not and do not plan to change the stereo deck itself. Read something about that and pretty much stopped when it said dealer. Thankes again.
