Using the relays that come with the Rigid Lights

Is it a bad idea to use the relays that come with the rigid light wiring harness? I just connected the hot lead and the Blue wire to the upfitter pass thru and left the one wire (black I beleive) disconnected.

I know we already have relays in our vehicles for upfitters, but was not sure if I was going to lose voltage by running two relays.

How did you guys do it? did you remove the relay portion of the wiring harness?

Harness came with relays and their switch. Since we get powe from the upfitter I had to by pass their switch. I ran the hot to the relay and the hot wire from the switch, with the neutral to the one upfitter wire. Their switch is tied into their relay. I left off one wire from the harness that went to the unused Rigid switch and everything works fine. This is all I got from rigid. (see Attached)

You are Correct...It was the illumination lamp wire for their switch. I multi metered everything out and that is what it showed. But I was worried or wondered if there was any issue of using the Rigid harness including their relay since we already have relays in our upfitter. I don't think I am going to see much voltage drop by tying it into the upfitter wires, instead of running wire to the relay the hot right to the battery and just using the upfitter to replace their switch.

ok, the relay is for connecting power straight to the battery, because there is an inline fuse they were expecting you to connect to the battery. the other wire would be what we call a turn on wire. that wire provides power to activate the relay and that should be connected to your switch. there shouldnt be any voltage drop if you connected directly to those switches, but the wires might get hot. my guess is that those power and ground wires are pretty thick. that has to accomodate for the amount of current draw the lights have. your best bet would be to connect the way they want you to.
