The original wiring in the car harness will have a wire that's Dark Green with a Red stripe. That's the 12volt signal from the radio to turn the amp on. Your aftermarket radio/wiring harness will most likely have a Blue or Blue/White wire that's for the amp turn on. Check the manual for your aftermarket radio to verify what wire it actually is and connect that to the Dark Green/Red wire in the car harness.
