I checked out the relay panel you posted. Nice setup. Can you help me understand why you would use that over just the upfitters? Need for more amperage?
Most use it for one of 2 reasons
1) They need more amperage
2) They want to control which light circuits come on/off with their high beams.
I use it for more amperage on our demo truck as I'm running 4x LP9 off 1 switch.
However I actually wired 2x LP9 to 1 relay on the LVJ, the other 2x LP9 to another relay on the LVJ.
I then connected 1 upfitter to BOTH relay triggers. This way I can turn 4x LP9 on from 1 upfitter.
WHY did I split them though? In case I ever want to put different lenses in and run them on different switches, I'm already setup for it easily. Plus i'm also not overloading the LVJ system by having so many lights on 1.
I actually have the low modes on 2 relays as well so when im ready, i can tie in my high beams to it.
