I'm installing a new head unit in my 87' Crown Vic, and need a little help with the wiring. I was able to successfully get power to the unit, but am having trouble finding the wires leading to the speakers. The only wires that I figure could lead to the speakers are the 5 that are coming out of the back left side of the origional head unit, right? Well, I get no response from these wires, not to mention the fact that that isn't even enough wires for all the speakers in the the car. If anyone can supply me with info on where these speaker wires are located, or where I can get a diagram, that would be a big help. Infact, any info. would be a big help!!!

Now, you do have the orange wire for accsesories and the red one for power, then the black will work right off the frame. For me, the rest was trial and error. Have fun.
