I have a 97 150 with the stock baseline tape deck with no factory amp, and four speakers. My question is what are the colors of the wires for each speaker, negative and positive at the back of the stock headunit. Im going to put a cd player in place. Thanks in advance, Chris

 

Installdr.com might have a wiring scheme that would work for you

 

I'm installing a CD player right now in my 2000 F-150. These should be the same. Here is a link to a Crutchfield receiver installation guide. I think the colors are pretty standard; http://akamaipix.crutchfield.com/ca/...iver_guide.pdf

Violet- right rear positive
Violet/black- right rear negative
grey- front right positive
grey/black- right front negative
green- left rear positive
