Fog light question.

[Aviator]

I have an 84 325e and I've converted it over to euro bumpers and I have a m tech 1 front with fog lights that I'll be installing soon. I have a fog light switch inside the car that lights up when I push it, but I cant find any wires that would've been for the fog lights up front or under the car. So can I use the extra two wires that are tucked away that used to be for the front/side parking lights? Then the fogs will be on when I turn on the parking lights? Would I need to use a bigger fuse since the fog lights are a brighter bulb? Thanks.

I don't know if the '84 is different, but on my '87 the fog light plugs were tied to the wire harness on either side of the car that leads to the headlights.

Hmm, I'll have to take a look.

I can take a picture of my pigtails tomorrow as long as it isn't snow/sleet/raining like today.

[Aviator]

Ok that would be great if ya could thanks.

Here are the pictures:
This is the driver's side plug. It's located just rear of the headlight assembly tied to the wire harness.


This is the passenger's side plug. It's located behind the headlight grille near the center of the car. This side had a longer pigtail on my car, which made it easier to attach without cutting any factory zipties or anything.

Ok thanks. Whenever I see my car again I'll look for them.

Whatever you do, DO NOT replace a fuse with a higher rated one. The fuses are their to protect the wiring. If you put a higher rated fuse and something shorts, the wire will burn before the fuse will and can cause a fire.

This shouldn't be an issue now as the fog lights will run separately from the running lights when he finds the plugs, but this is very sound advice nonetheless.

[Aviator]

Yeah thanks for the advice. Hopefully I can find the plugs and all works like its supposed to.

Ok I found the plugs. And when I put in the fog light plugs in they dont come on when I hit the fog light switch. Fog light fuse 29 and 30 are good. Fog light relay bad?

[ELVA164]

You sure the bulbs are good? Otherwise check the relay. If it isn't a relay with a diode in it, it won't work correctly.

Bulbs are good. Fog's from an 88 m3 to fit the M Tech 1 kit. Euro smiley's
