Thank you for that information, will help me figure this out. No, no blue/white wire; just a red/white (power always on) and a brown/red wire that seems to be a ground. ... Though the wire going to the horn maybe incorrect!! The red/white makes sense going to the horn (always powered on), wondering if the wire that is connected to the horn could be it!! Will hav to check this out!!Prisma goes on when the parking lights/head lights go on so check that. Do you have a blue/white wire in there?
I would totally take a 17 x 36 print out!! If you are serious.There used to be an easy to find wiring schematic on this website- maybe someone will volunteer on how to find it for you. It shows the wire, the source, the color, the gauge. If you want a 17” x 36” schematic in print - LMK
Wow - this is amazing detail and informationYou don’t mean here do you? lol
