Wiring Test 3 Update! AMP enable from Headunit

After pulling the HU and disconnecting the 10 pin harness I located the brown with silver stripe wire and de-pinned it.

I wrapped a extra 18gauge wire around the pin. I didnt want to cut anything at this point. And used heat shrink to seal it up.

I attached the the new wire to antenna signal 12v line with a tap.

I checked the voltage at the amp connector with the car off and on.

Car off = 0v
Car on = 12v

I reconnected the factory AMP harness and powered on the car, everything worked correctly and the once disabled Factory AMP was 100% functional.
