The easiest signal for me would be a digital signal of 0 or 1 coming from the IBus for activation.  |
I remember reading something about a tap into the wire that powers the PDC indicator light. IIRC, this pick off can be made in the vicinity of the wiring harness near the battery. A review of camera install posts may reveal the actual description details.
