Need: taillight wiring diagrams for Jetta

[A2Carat]

Hooking up a rear fog and noticed there are 4 wires to the inner bulb tray (trunk lid) that only has a reverse bulb. Are the cars wired for rear fogs but the lenses not drill for bulbs?

Just need the wiring diag. please! Thanks!

those are extra brake lights not used in the NA market

93 and 94 all you got to do is drill out the lenses and put the bulbs in

all later cars these sockets dont have ground or power, it would take a little more to get them functional

and they are in the same spot as rear fogs

Here's the North American tail light wiring diagram for 1996 and 1997...:

...the German Vento tail light wiring diagram...:

...and the German Vento rear fog light diagram:

The rear fog light is Nebelschlussleuchte, abbreviated NSL in the lower-right corner of the last diagram.

Looks like it's wired into the #12 terminal of the European light switch; no relay.

I hooked all this up on our 1997 Jetta 12 years ago.

The single rear fog light goes, of course, only in the left-side tail light housing. I had to drill out a hole in the reflector for the bulb, but I seem to remember that the bulb holder was all there ready for the bulb. I did have to run the +12v wire up to the switch, though, under the trim under the doors.

Thanks you so much. That is way more than I asked and a ton helpful. The bulb trays in my 98 have the socket for the bulbs, just need to hook up the wiring. Thinking of just wiring them into the front fogs. If not, just turn them into brake lights.

Thanks again!

looks good. Maybe you can make a DIY when you're doing this? I'd like to see if possible.

You're welcome.

If you want to do it right (besides just mounting the one rear fog light on the driver's side), you really ought to spring for a European light switch that can operate the rear fog light properly. U.S. FMVSS regulations don't care, but EU regulations require that it be operated separately from the front fog lights. Good reason for that -- the rear fog light aims straight to the rear, and is quite bright; it can really blind or at least annoy the driver behind you unless the fog is really dense... EU regulations prohibit rear fog light use unless visibility is 50 meters or less; front fog lights can be switched on with 100m visibility.

You're right. I don't want to hinder anyone elses ability to see .. I was thinking of using the stock fog light, but wire in a switch to the power to the rear - in series. So if the front fogs are on with the switch on, then both come on, but if the front fogs are switched on and the rear fog switch is off .. well, you get the idea. I was also thinking going the brake light route. Either way, I'll post pictures and a slight DIY that was requested in this thread. Thanks again.
