Does anyone know what color the remote switch wire is on the shaker amplifiers? I am hooking up an external amplifier to the existing system for subs, and want the amp to turn on with the radio. I realize it is only 5V, but my plan is to use a 5V relay to switch the 12V battery voltage. I just need to know which wire on the Shaker's amplifier to tap into.

 

Circuit 173 - dark green/violet stripe should do it-check with DVoM before tapping.
