I recently got myself an 88 Sportruck Comanche and I need to wire in a radio since there was not one in it. There was no stock connector just 13 wires that were cut. The colors are as followed: Black, Red/Pink, Violet/Orange, Blue/White, Black/Yellow, Orange/Black, Brown/White, Brown, Green/White, Green, another black, a White, and a white/black wire. My problem is I know the power, ground, and accessory, but not the speaker wires. I've tried three separate radios with several tries and no sound from any wire.
