I picked up a used set of OEM driving lights wit a 5 pin relay and wish to wire it to the high beams. Bare with me as I'm an electrical noob

WHAT I THINK I KNOW (correct me if I'm wrong)
Each driving light has a red and brown wire. I'm assuming the red is positive and brown is ground.

As for the relay, I understand that 86 is ground, 30 is to the 12v source, 87 to the remote line, 85 to lights, and 87a is left alone. Please advise on how to properly wire this.



QUESTIONS:
Do I join the two red wires to one line and hook it to 85 on the relay?

What do I do with the brown line on each lamp? Are they ground and should they be grounded separately on each side of the light?

If not using a remote or switch, do I just connect 30 to the high beams and leave 87 alone?

Thanks!

Thanks rkw but it doesn't since I don't have the wiring harness and I'm planning to wire it to the high beams.

 

30 would be your 12 v source. 87 would go to both your driving light.
85 would normally go to a switch, but in your case if you want them on every time you hit the high beams, that would go to one of the wires going to the factory high beams. 86 would go to chassis ground. 87a would not be used, this terminal would have 12 v on it when the relay was off, it is a normally closed contact. When the relay turns on ( you put high beams on ) 87 will have 12v and 87a would go to 0 v. When the relay turns on, it closes the contact to 87 and opens the contact to 87a. You should fuse you wire going to #30 within 12 inches of where ever you pick up your 12 v from, just in case that wire should short out going to the relay or the lights and you should use 10 gauge wire for the 12v source. You should run two separate wires from the lights to the relay and join them together at the relay. All the other wires can be 14 gauge.
Hope this isn't MORE than you were asking for help with...LOL

 

Hey Outlaw, can you be more specific?

 

Exactly the kind of information an electrical noob like me needs Outlaw. You kick a$$ man. THANKS!

 

Got it all wired up and everything works fine. Only question I have is what size fuse to use? Running a 14 gauge wire to the fuse box power source. Or should I just tap the cigarette lighter wire since that's already fused ?

Thanks

 

the factory install runs the power takeoff to the fuse box power lead and calls for a 15 amp in line fuse on the line.

Just as an FYI. The driving lights, when wired using the harness, only come on with the high beams. I know you didnt have the harness but figured it would give a little insight. Doing it your way is far simpler then using the harness to wire them in. That was a major PITA.

 

Thanks Capt!

That's interesting hunter. I thought it had its own switch. I'm actually thinking of picking up a switch as well instead of wiring it to the high beams.

 

They do have their own switch but it only gets power when the High beams are on

 

I like complete manual control of driving lights, but keep in mind that many states only allow driving lights to be used when you're running your regular low beams and running driving lights with high beams on is often illegal. Your state may vary.

 

I actually bought a set of OEM driving light and modified the wiring so I could control them, but yes, you have to be careful about the states/country rules. Hell, some places you can't drive with fog lights on all the time :s

 

It's exactly the opposite. Auxiliary driving lights are like an extra set of high beams. You can turn them on only when it is appropriate to also use high beams. That's why the OEM driving lights operate that way. When you turn them on, you should have low, high, and driving lights on together at the same time.

 

Totally forgot to mention that.
