I'm in the middle of my Volvo swap, and I don't have access to any of the wiring diagrams I need. My motor/trans is from an '04 Buick Rainier, 5.3l. Coming out of the PRNDL switch, there are 3 wires that were going to the C2 fusebox plug - light green, grey, and yellow. Anybody know what they are? My guess is some kind of either serial data/CAN, or some kind of gear selection wiring from the stock cluster. Can anybody help? Thanks!!

 

Anybody???
