RAP wiring question
:banghead: Installed an Alpine XM rf modulator last night. I could not find a 12 volt delayed accessory power line in or around the console. Running out of time (2 kids + wife), I used a switched 12 volt connection that went ot the (auto) a/c panel. The a/c was off at the time. Buttoned everything back up, backed out of the garage this a.m. with the XM on. When I turned on the a/c, the XM went off?? Turn the a/c off, and you can turn XM back on. I know engineers sit around and think of stuff like this to do to us. Anyway, I would really like a delayed accessory source so the radio and XM stay on until a door is opened (like I did in my wife's car). Any suggestions? I hunted around in the fuse box briefly and without success, but that is tricky with all the doors closed.
Thank ya'll

Re: RAP wiring question (TERMN8R)
Gary,
I have heard that Chevy built in a set of wires for connecting aftermarket electronics. I don't know if all years have this feature, But it would be easy to check.
Remove passenger floormat, unlatch and remove fuse access plate. Look for a set of taped off wires, (red, yellow, and black) They are constant 12v (red), Turn-on voltage(yellow), and ground (black). It should retain power like factory stereo (I hope).
I read this tip on the forum, so I would assume it's kosher. I'll have to go home and check mine to be sure!
Good luck

Re: RAP wiring question (TERMN8R)
I used rockrz's suggestion, there are three wires just above the computer near the inside fuses that are 1) switched, 2) continuous, and 3) ground. I would still like to have RAP to the XM, but at least now everything works.
Thanks for the responses

Re: RAP wiring question (TERMN8R)
The power in the footwell for accessories is not RAP power. It turns off when the key is turned off immediately. The only place I could find RAP power was the antenna and the power windows. Tap into on of those. You could trace back a harness through the doors, or open up the trim panel behind the drivers seat and grab the power off the diversity antenna module (I did this). Works fine.
