Does anyone know the pinout for the connectors on a "Ford Sound 2000" car radio cassette. I took it from my 1990 Sierra (along with the plugs that went into the wiring loom) when I broke it up and scrapped it recently and want to stick it in my campervan, but can't identify the wires. One connector has eight pins and this is most likely the speakers, the other connector has 7 wires, two brown wires, one red, grey, yellow and red/white. I'm tempted to connect the negative from a power supply to the radio chassis and take a chance on the red being positive, but put you never can be sure on car stuff. Might be brown?
I've tried all sorts of searches on google, but can't find anything.
