2003 Monte Carlo remote/switched 12v wire?

This is for a 2003 Monte Carlo-

Assuming a stock GM deck and factory rear amp, is there any wire i can tap into from the trunk or under the dash (not under the hood, unless i have to), that i can use as a remote wire?

End-path will be the trunk, and as always, the shorter and easier to get to the better...

thank you!

Not my car, i don't really care about getting a new head unit for the vehicle, unless he buy's my Pioneer 7600 im sellin.

I just want to get something to make the amp kick on. I tried tapping the blue/white wire thats on the factory amp, and whenever the bass hits on the 6x9's the amp's lighted face would light up. Needless to say it was rather cool, but didn't allow the subs to play.

Soo, If i tap the orange wire from the ignition harness (? location?) and run it as the remote wire? I wanted to say orange or pink, but i thought the pink was used to crank it over. I have a 1997 monte carlo personally, and i really don't like messing with the 2003 factory wiring and amp, its a pain in the butt. I will recommend getting an aftermarket deck, however i think his funds are rather short. When his funds pick up I may try to sell him my deck for ~$150 or so, but until then the orange wire probably will work. I have not tested any wires up front yet for switched, and i didn't want to run them off anything that wasnt switched (obviously).

Thanks for your help, next time i get a chance with the car i'll test it with the DMM and hook it up if it works!

So DARK BROWN is better than Orange?

On the ignition harness, i guess the forum labels them as ACCESSORY /HEATER and Accessory 2/heater...

I just don't want a remote wire that kicks on only when the heater is on. an Accessory wire is what i wanted, however. Sounds like either should work alright, i only need 50-200mA to kick an amp on..

the brown does air conditioning and i personally preffer orange b/c it is what runs the accessory equipmment in the vehicle no big deal actually just preference
