Re: Light bar question
I would have a dual relay/switch set up.
The first switch would be controlled buy the reverse lights. I would run a jumper from a factory reverse light to a relay that would engage to have them come on automatically. I would then have another relay controlled buy a manual switch on my dash.
Both relays would be powered from the same constant 12V source. On the output side I would run a jumper from one relay to the other then one power wire to the bar.
This would keep you from shorting the system.
