Got at set of driving lights for my F-150 super crew. The light kit came with relay etc. I want the driving lights to come on with the high beams and go off with the low beams. I know I need to attach the wire that gives power to the relay some where in the high beam light circut to make thing go the way I want, but where is that attachment point? Where would be the best place to tie into the high beam circut????????

 

Anyone know where I can find a wiring diagram for a 202 F-150, then maybe I can figure it out my self???????????

 

I have my driving lights (Hella 550's) wired in to come on with my high beams only. Sounds like the same thing you're looking for. Since you're using a relay - which you should - you'll have one powered wire that goes to a 12 volt source. You'll have another that goes to the circuit you want to "signal" the relay to kick on with. For that, I used the hot wire leading to the high beam filament on your headlight harness. I don't remember off hand which color that was, but you can find it easily with a test light.

One other caution. When you jump into that hot lead, make sure you don't just strip a section of wire and wrap the lead around it. (I've seen that one before.) Use an approved method of splicing in and you'll be much happier down the road.
