I have an aftermarket stereo hooked up to the bose system. Was like this when I bought it. I just replaced the headunit, and wanted to clean up some of the wires - in the process I disconnected the Amp Turn-on Relay which was flating around behind headunit. How does this get reconnected? there are 5 prongs on the back - which wires go where?

Currently - without the Amp-turn on relay - the radio turns on - ant up- but no sound - obviously.
