2nd Gen Non-Engine/Transmission Wiring driving lights to highbeams

[FFSchooley]

I am wiring some off road lights and want to have them activate when the highbeams come on. What color wire am I looking for and where is an easy place to access it to run a wire to my switch? I'm sure I could find it but I was hoping for a quick answer rather than spending a few hours under the hood. Its 105 out today. Thanks in advance!

That is how I did mine. Under the hood left head light there are three wires. On the plug it is marked A,B,C, A is power,B is low beam control ,C is high beam control. D/C turns lights on/off with there grounds. The C wire should be RD/OR, connect the ground wire from your driving light relay to this wire. The relay + connector to power. The relay should turn your driving lights on with the high beams now. provided you have run power through the relay to the driving lights

Just a word of caution. I'm 99% sure that DC didn't go to a switched ground until the '99 model year. FFSchooley, since your truck is a '98. 5, I think it should still be a positive switched system.

I would put in a 3-way switch so you can turn the driving lights off or even set it up so you can run either or both. Be sure to run them off a relay so as not to load your already weak wiring.

Does anyone know how this would work if you are running a Brite Box? I would like to have my driving lights come on with the high beams but how would my Brite Box effect this? I have aftermarket driving lights not OEM.

The bright box uses the same signal to turn the low beams back on

Hunter11,



On my model year 2000 Ram I'm running the BriteBox, PIAA 60XT driving lamps powered by a relay that uses the switched ground on the high beams, and OEM fog lights that work with both low and high beams. When I switch to high beams they're all lit. Thirty plus months with this setup and no problems.
