The relay comes with a diagram.

Sorry, need one wire only: the 12v red (in the engine compartment) leading to the hitch. The hitch is powered ALL the time. I need the relay inline with this red wire, and I do not want to put the relay at the hitch end. I have the wiring diagram for the relay. I have the Helm manuals. I have a butt load of wires in cable looms after running my roof lights, grille lights, reverse light, and rear fog light. Have a look through your Helm manuals, or have a look here for the magical wire:



Steve - SanJose ... next time you are making happy snaps of your H3 could I trouble you to grab one of your engine compartment by the battery. Or do you know where your installer installed the relay for your HitchCAM?
