xm install, delay accessory wire
 

Just installed an xm using the p.i.e. Sounds great, but I wired the power to the cig. lighter which is alway on. To prevent the potental battery drain I would like to wire this so that it turns off when the radio is off, which is a delay off or off when the door is opened. Anybody know what wire this is? I have an '04 with the 6 disc in the dash.
Thanks.

The power wire to the radio should work, just check it with a multimeter.

Welcome to the site!

Ty, thanks but there's alot of wires going to the head unit. Which one is the power wire?

it should be a bit thicker than the rest of the wires, but not the black ground wire with the spader terminal.

I think its yellow?

If it helps the wiring harness on the Pioneer radio I just installed has a Red wire for continuous power and an Orange wire to the switched, or ACC source.

From what I can see in the wiring diagram its a Pink wire with a black stripe. Should be powered by fuse #2. I put in a 2004 150 2wd. It dosent diffrentiate between radios on this wire.

I would go with what ngm said. I must have been thinking of one of my buddies cars.
