Only one way to find out... test light. My guess would be:

 

Red = ignition

Blue = remote turn on or antenna turn on

Black = ground

Yellow = constant power/memory

White = illumination

Don't cut the red one or that thing will turn into an 8-track!

get a good auto repair manual with an exact wiring description of your truck and look there for best results.

thats what i thought but they also have something to due with sound these wires are the pin out from the cassete player to the stereo i made another cable to try to turn it into a 3.5 mm headphone jack to the 5pin din cable it need and i figured out the ground cable and the left speaker cable but when i plug in what i assume to be the left speaker it cuts out completely kinda like when you play a tape but it doesnt play anything at all so im still gonna play around with it and if i figure it out ill do a write up on it

so I am guessing the cassete is a separate unit. does the cassete part have any other plugs or wires? if not then I would say the red is power, blue is audio ground, black is ground, yellow and white are audio positives.

the cassette player has a separate plug for power and ground

then one wire is frame ground, then the other 4 are pos and negs for left and right. try this: 2 left+, 6 left-,9 right+, 4 right- and see where that gets you.
