I have a 2008 S550 sitting here helping a friend to re-wire. We got all the wiring ran for the Valentine 1 Radar system already but need to tap a 12v+ Ignition wire that only shows power when the car is on (started and running).

Is there a simple and easy place to find this 12v+ wire?


thanks!

I jammed the wire into the harness of the cigarette lighter to get power. I didn't want to cut any wires..

Try it out..
