Can anyone tell me where I can find the RAP wire? I installed an XM radio and I want to power it from the RAP rather then the lighter. I looked around but I have been unable to find it.

On a side note, after I put the radio back in the dash after hooking up the xm direct adapter I lost most of the lighting in the LCD display. What a nightmare to fix. I got the front off and found that 2 of the bulbs for the LCD display were out and 3 others bulbs were out. I replaced them all with parts from an old Pontiac radio I had and it looks great but it was a lot of hassle to do and you have to be very careful not to break and wires to the display board (I did but I was able to fix them).

Thanks,

I don't know what the RAP wire is, but please note that your XM radio runs 5 volts and that there is a step down transformer in the XM radio cig lighter adapter to convert 12 VDC to 5VDC. To hardwire in a aftermarket external XM/ SIRIUS radio one requires a step down adapter.

The RAP is the retained accessory power. I am just going to take the lighter adapter apart and solder leads to it once I find the RAP wire then tuck it behind the dash with the xm direct adapter.

Tap off of the radio'* 12v power. Not BATT power but the other one. That should be RAP.

one of the radio wires should be yes. the fuses and relay for that are under the rear seat

The radio uses the dock and lock, so all I see is a ribbon cable. I would like to find the rap cable somewhere under the dash rather then having to run a wire back to the fuse block.

Thanks jwfirebird

So there is a fuse at the instrument panel. Looks like yellow wire feeds the rap to the radio.

I never could find a wire under the dash that worked. probed every yellow wire I could find. On my car a blue wire leaving the fuse box under the backseat had to be used. I am sure the rap exists someplace else but I got tired of messing with it.

thanks for the update
