First Gen Gs300 Remote Amp/antenna Wire?

[landolakes]

I am installing a aftermarket pioneer radio, and i want to use the factory amp. My problem is that I cannot find which wire is turns on the factory amps when the radio is turned on so i can connect my remote wire to it.

also the power antenna i see that there are a few wires to power it up, i want it to be functional..

For the amp just locate the amp and take a look at the color of the wires.

Did you cut your vehicles wiring harness or do you have a plug?
