Ok sorry if it's a dumb question but I bought a xj with rock lights but one doesn't work so ima change it out. I know there's the lights. Some wires. A fuse and a switch. How does it all work?

 

 

Could I make it simpler and do fog light ground the negative positive goes to a fuse then a switch and battery without doing the relay or any of that other stuff

 

Relays prevent fires....

 

Only if you want to melt your wires and potentially burn your rig to the ground.

 

Why will it burn down if it blows the fuse and shuts it off??? Could I use one of the fuse able relays when they get overloaded they shut off then turn back on

 

Is hooking up a 4 prong relay that hard?

 

Damn just wondering.

 

Is it worth a few buck rather then having to buy a new Jeep???

 

No I was just curious

 

Relays are the most over looked thing on any aftermarket light. I have a relay per light on my jeep. I also have 12 off road lights. I made a relay center.

You can hook it up how ever you want. With what we told you you can't come on complaining how your harness is toast cause you didn't use a relay. Lol

 

So why is there a 20 amp fuse hooked to the relay but the switch is hook to the fuse box????
