HELP Light bar to turn on with Perimeter Lighting

[VTSTOMPER]

VT:

What are the perimeter lights? Do you mean your DRL/reverse lamps when you unlock the truck in the dark?

I imagine you would need to put in a second "hot" line that would be spliced into that circuit’s positive line. I do not know if I would do that - only because the watts on that light bar are probably more than the wires were designed for.

Is it a factory bar?

Here is the relay set up to make light bars work with DRL's. Remerber when going from relay number two in pin 86 is a good idea to use a diode. wiring it this way will make sure that the light bar only comes on at night when you push the buttons on the key fob.
