In-Dash question

Seriously, did you even look at the install manual? the wire(s) labeled "PARKING BRAKE (-)"/"BRAKE (+)" are the wires you are looking for. If you have only a "PARKING BRAKE (-)" then you should wire it to a switch that connect it to (-) NEGATIVE power. If you have both, you will need a slightly more complicated arrangement to fool the unit into believing it is parked.
