I need help wiring my light bar. Does anyone have a easy to understand diagram?

 

A little to vague. How many lights? How many watts? Are you using relays? How many switches?

 

It's easy, you have to complete the circuit.

Positive: battery -> fuse -> + side of lights
Negative: - side lights -> switch -> ground.

Or

Positive: + side battery -> fuse -> switch -> lights
Negative: - side or ground -> - side of lights

Edit: assuming you're doing mild lighting

 

Here's wiring up an LED light bar.


This should be pretty easy to understand.

 

What kind of relay do i need and where can i get one?

 

72watt light bar

 

How many amps is that?

 

Damn i honestly cant remember:/

 

Light bars don't pull much at all. Especially a 72W one. Any parts store sells plain ole 4 pin relays for a couple bucks. Or any 5 pin relay will work. Just ignore the center pin.

 

Holy hell go to autozone, get a 30/40a accessory relay and some crimp style connectors. Use 12ga. Wiring or 10 if you're gonna ever upgrade. 72w/12v=6a. You can wire it in an hour slightly more I you have to still mount light bar

 

Damn you beating me lol

 

You provided the math for amperage. So you win.

 

Cool. What do I win

 

 

Nice
