    hi, im looking for a radio schematic for my 1997 buick lesabre custom. my brother decided to cut off the connector instead of buying the adapter… well anyway. there is 18 wires coming out into the harness that originally plugged into the adapter. your diagram has like 15 or 16. im not sure what they all are. so any help would be greatly appreciated. there are multiple of the same colors. two blacks. 3 dark greens. and 2 light greens and such. i didn’t know if i should splice them all together or not. so any help would be greatly appreciated. thank you so much,

    I need to find the location and wire color of the Vechicle Speed Sensor (VSS) wire so I can install an indash Nav system. This is for a 2006 Rendezvous.

    Adam, use the dark green wire located at the PCM module. That is the Speed Sense wire for your 2006 Buick Rendezvous. The PCM module is located inside the air cleaner assembly. Hope this helps. Good luck.

    Debra, most door panel removals can be done with a Phillips screwdriver and door trim removal tools. Just look for screws at the edge of the door panel, near the door handle or inside the door pull. Once you remove all the screws or plastic tabs, you should be able to use the door trim removal tools to pull the door panel off with ease. Hope this helps. Good luck with your 1993 Buick Century door panel removal and speaker installation.
