Off Road Light Wiring... HELP???

[ItsMeKO3]

Does this diagram seem correct? I've seen some that have a 30amp inline fuse between the relay and the battery I believe? Will I need that also?

Fuses never really hurt you can throw one in if you want it won't effect anything can only help if something goes wrong or gets shorted for any reason.

You definitely want a fuse between the battery and relay. Also I always throw a small fusible link with a fast burn 10amp fuse between the switch And its power source... especially if you're running it off an accessory wire under the dash.

Ok I'll have to pick up an inline fuse before I start the wiring. I've read the instructions from Hella, and they have you wire the lights to the high beam. Instead of using the high beam can I just tap into the parking lights using the wire they want to be used to tie into the highs? This way the aux lights can be run on their own switch, but only when the parking lights are on? I want to do this just in case I leave them on, they'll be turned off with my headlights. Sorry for all the questions guys, I just want to have a good idea of what I'm doing before I try to tackle this.

Normally you want to be able to control the lights independently for all of your factory lights since there are circumstances that you wont Want them on...

The best way, IMO, to prevent accidentally leaving them on is to power the switch via an accessory wire leading to the steering column. That way the switch can't get power when the ignition is off.

Three things to consider though;
1) warranty. Tapping into the OEM harness has its obvious concerns if you're still under warranty, should you have any electrical issues directly related to that harness.

2) I would put a fuse there so you don't blow the entire circuits fuse is something shorts. (Hence a 10amp quick burn fuse).

3) I wire my switches from a constant 12v source. I don't like the idea of leaving my keys in the ignition while I'm using the lights and I'm not in the Jeep (say helping someone on the side of the road at night.... then someone could hop in the Jeep And drive off while I'm changing someones tire...)

Here is another diagram I've found, this one seems to be the one I need to follow??



My question about this one is what is the white supply wire from the switch going to the "Hi Low Ign" going to? Is this the wire I need to tie into a 12v source? Some guys say they use the cigarette lighter...?

[ItsMeKO3]

^^ Read some more about that. By tapping into the cigarette lighter, you must have keys in the ignition to run the lights? Which is what you said you didn't like Matt because someone could steal your Jeep. So where should I tie into? Again, forgive me for all the questions, I really don't know much about wiring so I'm trying to get it right before I start.
