Anyone have any suggestions about hooking up the lights,like where to get the 12v for the switch to power the lights? I'll use the 12v right off the battery to power the Relay,and ground right to the batteries neg.term..
I'd use the switch to activate the ground terminal of the relay, much easier to find a grounding point in the interior than a 12V plus no splicing required. Use the 12V under the hood and link the 2 hots on the relay together. Just my opinion.

The Matrix Pushbar looks nice and cant wait to see pics when you get the rock guards.
