I'm looking for a set of foglights for my Mk3 Jetta. Prefferabpy in the Edmonton area. Anybody with anything msg it back!! Also any suggestions with what I can do with those lights. Any ideas!?
For a OEM fog set up you'll need:
The headlight harness in single chamber (Jetta, or Golf) or dual chamber ( GTI, some golfs) easiest way to tell is if you have 1 headlight bulb or 2.
The Fog lights
15 amp blue fuse
Both of those ^ go in spot 10 on the fuse box. I'll link you a picture of the MK3 fuse box.
Headlight switch with Fog option.
But be aware that you don't have to run the wiring through a relay and fuse on the fuse panel under the driver's side dashboard. That's the way the stock fog lights were wired on the GLX, but it's kind of tough to get at the fuse panel and do the wiring there.
What I did on our '97 Jetta GLS (rather, had the VW dealership do back in 1996) was to install a separate wiring harness with relay and fuse. It's controlled by the Euro switch as usual, but the wiring runs straight out to the engine compartment where the relay, fuse, and secondary circuit controlling the lights are all located.
You may be able to find "universal" harnesses that will do that, which will make the wiring much, much easier. Or get one of the Mk5 aftermarket harnesses from ECS Tuning that are meant for the "non-CECM method" on Mk5's, like this:
All you'd have to do is get the appropriate foglight connectors and terminal pin for the light switch from your VW dealer, and splice them onto the ends of the wires.
Another noob here. Instead of starting a new thread about this I thought I'd just nudge in... I want to fit fog lights in my Vento. My switch already has the pull-out knob for the rear fog. Is a different switch required for front fogs? ... also how do you go about attaching them to the bumper, I can see where the screw holes would line up but do I need clips or something?
Because to retrofit Factory fogs, only requires touching the headlight harness wiring wise. ALL the other wiring is there from the factory. Run grounds from fogs to the headlight harness connector, power from fogs to the headlight harness connector, pop a 110 relay in the fuseblock, and pop in a fog switch and you are done.
There is/was even a factory add on harness exactly for this. Its a 1hr job, if that.
I'll take a look this weekend, but I've never seen any fog light wiring harness there. And I'm fairly sure a fog light wire had to be added from the switch's NL terminal, but I'll look at that too.
I do concur, though, that the dealer wasn't real knowledgeable. When buying the car, I asked them to dealer-install "the same bumper-mounted fog lights that are on the GLX." Dealer: "Oh, yes, sir, we know exactly what you mean. We can do that."
When I picked up the car, they'd hung generic aftermarket fog lights from the bottom of the bumper. After cutting away two of the vertical ribs in the lower grille to make room.
Jeez. I told them to take those off, and had to go to their ETKA to show them the fog lights and parts I needed. They finally got it done, selling me the parts at cost. I didn't insist on them replacing the lower grille.
Yes, a different switch will be required. Your switch only controls your rear fog light, and EU regulations require that front fog light be controlled separately.
The fog lights mount to the holes you see in the bumper using what we call speed nuts:
The speed nuts are clipped over the holes, and the fog lights are secured with screws that thread through the holes in the speed nuts.
Note that fog lights made for North American mk3's won't fit into a European bumper without some modification.
