Radio Wiring Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

FLAGG · 08-22-2005, 09:32 PM

I pulled the stock GM AM/FM Tape Deck out of my '86 Sierra last night because it has some bad connections inside (electronic display doesn't work and the left side speaker connections were shot). Anyway, when I pulled out the radio there was the standard 3 pigtails with the four wire connections in the back, but there was one more lone two wire pigtail sticking out of the back of the radio unit. Does anyone know what the 2 wire pigtail is for? The wires coming out of the radio are orange and brown, and I believe the wires on the trucks pigtail were the same color. Thanks in advance.

orange one is constant 12v, the other is a dimmer wire thats tied in to the dash lights.

Bagged: I was thinking that, however the wiring diagram for the other connections is stamped into the housing on the radio and claims one 4 wire pigtails is DIM-ANT-GRD-12V+. Hence my confusion.
