Hey guys! I just installed a Ridgid Industries 10" light bar on my Commander. When I bring the red, blue & black wires back to my switch, the light that lights up my "switch" stays on. I don't want this to happen so I just didn't connect the black wire. I only connected the red & blue to power the light bar. Is it OK to not connect the black wire? I believe it's a ground. I have a relay & an in-line fuse in my wiring harness.
