Hi forum! I picked up an amp with intergrated high level input to avoid using a line out convertor. The high level input requires me to splice into left and right speaker for signal. Does anyone know which wires on the plug I should be tapping into too? I wanted to tap into the remote wire from the stock ML amp as well for the aftermarket amp. please help me locate those three signal off the stock amp?

 

this may or may not help. please use at your own risk

any other members wanna verify this is the correct one?
