Autopia Lighting Xenon White Fog Light Kit

Hey Mark (MSHardeman), I know this is an old post but just wanted to ask (if you even remember) a question...the fog lights you installed here you said you wired to an Isuzu fog light switch in the dash...how did you run wiring from the lights to the dash? Did you somehow use the existing fog light wiring already there and how did you pick into it before the steering column light switch already there? Or, did you run new separate wiring from the lights to the inside switch through the firewall?
Greatly appreciate the info, or from anyone who has done this...thanks!!
Elliott

VX4EGR, I'm trying to remember what I did for this, so if this gets to be a rambling post it's because I'm "talking" it out to myself as I go. The fog lights that I installed had a blue LED angel eye ring around them and from what I can remember, I wired those into the existing marker light wiring so that they come on with the running lights. The actual fog light part came with a wiring harness that I ran in the engine bay, to an auxillary fuse box (per Moncha's write up) for power, and then ran into the cabin, through the firewall, and then hooked that up to a stock Isuzu fog light switch (again per Moncha's write up). You can get the fog light switch out of a Honda Passport, or a Trooper (can't remember which years), or call Merlin and order a new one from him. I think I got my switch from Merlin, but I did clip the switch pigtail out of a Honda Passport that I found in a salvage yard. I did have to add one wire to the pigtail to make it compatible with the switch, but that was easier than creating a pigtail from scratch.

If you would like I can hunt down Moncha's write ups for you to go from. I know they helped me a lot.

Hope that helps. If you need any more info let me know.

MSHardeman, thank you for the info! What you wrote makes sense and is what I thought. I'm going through options for changing the fog lights but always wondered if it is even possible to use one of those Isuzu fog light push button switches inside but somewhere somehow tap into the wiring that is already there which is controled by the steering column light switch. In other words, normally when you flip that steering column switch, it first turns on marker and stock fog lights, then another turn adds your headlights. So what I'm thinking is somehow taking the fog light wiring out of that mix and running it to a separate Isuzu fog light switch added to the dash....then just adding a new/different fog light assembly to the bumper outside...thus having a separate switch controlling the fog lights, without having to run separate wiring through the engine bay and firewall to do that. Hopefully not confusing but perhaps someone here had either looked into it or done it with success?

I havent messed with that wiring before, but just off the top of my head, i know that the headlight fuse is under the hood and the fuse for the tail lights is in the cabin. I presume that the tail lights and fog lights are probably on the same circuit or at least activated from the same place, which means that the wiring most likely splits before going through the firewall.

That said... why bother? IMHO its not worth messing with the factory wiring behind the dashboard, its just too tight and easy to get messed up. its super easy to run wiring through the firewall, there is a very easily accessible grommet right in front of the steering wheel. No drilling required and protected by the hood and cowl overhang. You can even re-seal it with silicon if you are really concerned about water. I'm only 15 minutes from Collegeville, I would have no problem running the wiring for you someitme.

If it were me, I would put a waterproof relay under the hood that is fed power directly from the battery and going out directly to the new fog lights, and activated by the factory fog light switch. You can run a tiny 18 or 20 ga wire to the switch to activate the relay. Its easy to find a plug to match the factory fog lights, so you could even leave the factory wiring completely in tact, just cover it and secure it behind the bumper so if you ever want to go back, its simply unplug aftermarket, plug in factory.

Hey etl, you're probably right! Guess it's more work one way than another. I can run wiring no problem, just was looking for a logical in and out or something like that. Where are ya located out of curiousity? Every once in a while I see a VX on the road around the area...of course when that happens I'm never in mine!
