I got a 90 f150 and I am putting a cd player in it. I got my speakers hooked up but can't figure out how to hook up the power. My cd player has 4 power wires(hot, ground, memory, ant. ground) and my truck has 5 power wires( red blue green yellow and orange) I have tried every possible wire combo and blown the fuse a few times. I am stumped, please help

I really, really recommend you go down to Walmart, Best Buy, Circuit City, or any place that sells car audio and buy an aftermarket wiring harness adapter for $10-$15. They come with the wiring instructions and you don't have to cut into the factory plug. It also makes it very simple to swap radios if you ever need to. Here's the wiring info from my '88 Ford wiring manual-

Red- ground
Orange/black- lcd radio lighting (stock radio)
Yellow/black- switched power
Light Green/yellow- constant power (memory)
Light Blue/red- instrument illumination
