Connecting auxiliary lights
 
I have a 2007 WK Limited with OEM fog lights and I am trying to install a set of off road lights, but I am unsure about how to wire the lights. I would like to be able to turn on the off road lights through the fog light switch. Does anyone have experience with adding lights to their OEM fog light setup?

Also, some on this forum have stated that it is possible to have a dealer re-flash the computer to allow for the fog lights to stay on when high beams are on. Can anyone confirm this?

Any help is much appreciated!

As for the fog lights, you can wire them to come on with the fog lights, you may also want to check your local laws, in some states it is illegal to have fog lights on with your high beams.

As for wiring, you'll need a relay, standard 30A SPDT relay.

30-12v from battery
85-ground
86-12v from fog light harness
87-output to 12v lead of aux lights
87A-Not used.

What will happen is the 12v from the fog light lead will trigger the relay to active and connect pins 30 and 87 together therefore sending 12v down to your aux lights. You are using the relay to provide the proper power as well as act a switch.

I was not aware that some states require the fog lights to turn off when you engage the high beams. That's good to know! I guess I will have to go with my primary plan to run the off road lights with the low beams.

I am also wondering if it is perhaps a better idea to wire the new lights separately from the OEM lights and directly to/from the battery with a toggle switch and fuse. I like the idea of not having to mess around drawing wires and mounting a switch in the cabin, but it looks to me as if it is the easier and most safe solution.

The numerical positions that you list, do they reflect the power connections from the Power Distribution box? Sorry for being a bit slow on this :)

Thanks for the pointers and keep them coming!

You may also want to look fully into your states local laws on vehicle lighting. Alot of states have laws about how you may lights you can have at once, are the lights DOT approved, there is alot more to it then you would think. You may not get pulled over for them, but if you ever got pulled over for another reason the cop could call you out on them.

The positions listed are the terminals on a standard relay.

I would reccommend wiring them independantly to there own separate switch. Saguaro makes a nice switch panel.

Thanks for all the advice and info!
After talking to the local law enforcement, it appears there are no regulations in my particluar state which describe the operation of the off road lights. Although I can technically mount as many lights on the vehicle as I please, we are only allowed to use two lights in addition to normal driving lights when driving on public roads. I guess that would give me free range on how I want to wire these lights into the OEM system, but after some thought I have decided to have the off lights wired completely separate from the OEM lights. I think I would appreciate to be able to turn these lights on without having to turn the ignition, especially when camping and skinny dipping :)
Thanks again for all the help! You guys are great!
