I want to hard wire my xm radio and need to know what wire would be the best to tap into under the dash with out ripping all apart. I just want to find 12v wire that I can tap into that only has power with the key on. I will be wiring a "cig lighter style adapter" and pluging my xm original power cord in to that due to it being only 6v.

I want to make it so it only has power when the key is on.

My truck is a 97 xlt

Thanks...

 

You can tap into the accessory wire that turns your radio on when you turn the key to the on or accessory postion. I can't tell you which one that is, but somebody that recently installed an aftermarket systme could.....

I believe it's usually orange, yellow, or red.....I can't remember which one.

 

i

 

yellow wire... is the one you want if i remember

red is power that is always on
orange i think is hte dimmmer... but that one might be a big step..


but yellow should should work
Or i have the red and yellow fliped.. sorry

 

you can also get the ground in the same place
