oh, sorry. I hooked up an aftermarket amp and sub and need to know which wire to tap for remote. I cant remember which one I tapped, but I know it is the wrong one because my amp never turns off!
If you still have the stock HU installed you can tap into the RAP circuit under the IP fuse box.
Pull up the fuse box (two or three screws and a plastic clip), on the grey connector (C2) pins E10 and F10 (both orange, I used F10 since it was on the bottom row and easier to get at) supply 12V RAP power to the stock radio amps. Even if you have a new amp installed, the radio will still be telling RAP to stay energized. Use something like this to supply an automotive relay that you can connect to your "remote" wire on the amp.
Using this diagram as a guide:
-run the C2/F10 wire tap to pin 86
-connect pin 85 to a ground
-tap into your +12V source going to the amp and connect it to pin 87
-connect your "remote trigger" amp wire to pin 30
The amp will be powered through the wire you're using now, but it will be triggered from the relay which is pulled in whenever the radio is on (even after the car is turned off and Retained Accessory Power is still on).
