Foglight wiring question

[Steve 82SC]

I've recently updated my headlights and am in the process of installing Marcus Sucro's relay for the high and low beams so as not to stress the turn signal switch any longer.

My next project involves getting rid of the existing fog lights on my 82SC and replacing them with a more useable driving light which looks period correct.

Is there a relay for the foglights or do they run back through a switch as the stock headlight setup? If there's already a relay already in place, it would simplify the entire matter.
Thanks

The fog light relay for 82 is #2....counting front to back...in your relay run across the top of the fuse panel.....

Assuming you're going to use the existing wiring, if you want the new driving lights to come on with the high beams, there's a green wire that feeds the existing foglight circuit on the left low beam fuse. Move that wire to one of the high beam fuses and you're set! You can also move that same wire to the fuse that powers the license plate lamps and have your foglights come on with the parking lights. They'll stay on with low and high beams that way. The Euro cars are wired like this. Good luck!

I travel a fair bit for business, very often having to drive country roads at night. One of my biggest gripes is oncoming traffic with bright fog lights. These lights really do the owner at best no good, and at worst, blind oncoming traffic. Headlights are designed with a cutoff, this does not appear so with fogs. I swear some of these fogs must be 100 watts.

My suggestion is to leave them off except if you really do have fog and they actually do some good. If you must have them on for appearance, replace the bulb with a 5 watter, or hook them to the high beams. I certainly would have no objection to using driving lights wired to the high beams, but please, not the lows.

Foglights as a rule have a great, very defined cut off. The problem is the brain of the person installing them very often seems to be cut off also.

When you install them aimed to high, it gives you more light for normal driving but it isn't aimed with the considerations of a headlight. It also means they are aimed too high for use in fog.

Steve 82SC -> One thing to keep in mind when you are playing with the wiring is that the switches and the fuses are in an odd order in the Porsche. The circuit goes from the positive battery cable, to the switches, then to the fuses, and finally to the powered device. (Oh, and then to ground.)

If you need to build an auxiliary fuse/relay panel shoot me a message. I've got an easy, slick little panel that mounts like the factory panel and is easy to make.
