Could you post the links to those vids addressing the fogs ?

are you having the same issue? I believe he was referencing the end of the regular install video where he talked about the gray foglight wire and suggested moving it to another terminal, like post 11 I think he said.

I just wanted to know if the normal operation of the kit causes the foglight to trigger the high beams and if so, was it due to my wiring or the way the kit has to be designed and in turn, the fogs need to be placed elsewhere to correct that.

No, still trying to understand this, there have been multiple posts on fogs and Porsche appears to have tweaked the wiring more than once. The Jwest kit I bought a while ago is still on the shelf.

Simple answer is yes, the fog operation is disturbed when adding relays and/or LED bulbs.

The 911 fog light wiring has a couple of US iterations, and a few variations for other country deliveries. This is due to different laws governing the operation of fog lights. For the era of cars we are discussing, the fogs may not operate when the headlights are off, and they are almost always restricted from operating when the high-beams are selected. The high-beam issue is tricky, because the circuit uses the high-beam bulb filament as the ground for the fog relay, when power is applied the relay has +12V on both sides. That is one control version - there are others.

The most common update is to locate that control wire and ground it rather than running it through the high-beam circuit. But there are other variations where grounding what seems to be the similar wire will fry the harness, so I don't want to just add words to the instructions, have someone jump down and pick out that line and follow it out of context and melt stuff. Hooking up the relay as-is and dealing with fog operation later is the safe way to go.

Due to people not liking the government to tell them what to do;), we see the fog circuits have often been already modified and the relay kit causes no new change (or causes really weird operation).

I wish I could see each and every car personally and get them fixed up, but that is just not going to happen. The best I can offer is to send me message through my website/email with details of your issue and pictures of your wiring and I'll try to work through it. It is always solvable, but remote wiring on an unknown target is difficult.

Of course, that makes sense. I just wanted to know if like you said the fog light operation was disturbed by the addition of the relay kit. That at least tells me that I didn’t wire something incorrectly. I could sort out how to wire the fog lights after the fact, that’s not a problem. I will be happy to shoot you a picture of my fuse panel so you can take a look.

dictoresno - received your picture and further description - the issue with your high beams coming on with the fog lights is due to the LED headlights you installed.

The fix is to remove the White with Brown stripe wire from the high beam fuse and connect it to ground. This wire (from the fog light relay coil) would originally ground through the high beam light filament when the high beams are off. This does not happen with LED bulbs. The circuit is designed to turn off the fogs when high beams are selected, so this functionality is lost when grounding the white/brown wire permanently. There are fancy ways to add this function back, but this is part of change to LED bulbs, not my relay kit, and is too much for most people to handle or care about.

Got it. Just finished that actually just now. All sorted and working perfectly. Grounded the white/brown wire to the ground on the strut tower. Then installed LED H3’s and cleaned them up. Everything is great. Thanks for getting back to me! After watching your YouTube video again, I heard you mention the white with brown stripe wire and I noticed that I have it so I knew that that had to be the trigger.

My friend was having issues on his '87 with both the high and low beams on all the time. The contacts were worn in the turn signal dimmer switch. I put a new combo switch in along with LED's, and installed the JWest relays for him.
I'm not sure how the different years are wired, but the high and low now work properly, and the fog lights work properly. It has no W/Bn wire and they will go on and off independently of the high beams.
