Automatic Foglights

Ok the group of 3 15a fuses in line are what you used. The first one. However my fuel pump relay is under it and I think the fog lamp relay is powering my trailer lights/tail lamp parks.

Also, concerning those 3 15a fuses, they all go to the parking lights. From left to right is trailer parking lights, left side parking lights, right side parking lights.

I tried all 3 when I installed mine and it doesn't matter which you use, just whichever is easiest and not blocking other fuses (although the add-a-circuit will still work if there's other fuses above/below where you install it, as it sits higher off the panel). It just makes it so you don't have to pull the add-a-fuse if you need to check/change the fuse it's blocking.

Turn on your parking lights then pull each fuse individually and watch each side light go out according to which fuse you pulled.

Which pin is it going to? 87/85/86/30

In your pic above, move it to the left (lower left pin)

Yeah I read that on the diagram after. Sounds right. The lower left relay lead with the bevel facing front of car is pin 30 and has constant power. That is why it’s powering the parking lamps with them off.

Yeah I was dyslexic for a minute. Good to go now. Sorry and thanks for the help.

That wire is supposed to go to the bottom left pin on that relay. Look at the pic of mine in post #13, 5 posts before your pic. See the problem? You are running a constant +12v to your park lights.

This did not work for me. This actually turned on my tail lights. Parking lamps.

Is the wire to the relay on the wrong pin also? @08z71bgm figured it out.

I had a case of dyslexia. I was thinking left but did right. All good now.

Make sure it’s the left pin on the relay. Not the right. Lol

I did this with my fogs to come on as drl's

So I need some clarification. I did the wire from headlight relay to the fog relay and fogs do come on and stay on for high beams. However, they also are on with my daytime running lights. Is that how everyone else's are? Can this be corrected with the fuse tap off the parking lights? I also have a different # fog relay than other pics. I'm heading to the shop now so can add pics if needed.

Yes, if wired to the relay.

Yes, parking lights don't come on with DRLs, only by themselves or with the headlights.

I followed along with this thread because, I too, was interested in having my fog lights come on automatically. Using the add-a-circuit from my local auto parts store, I was able to tap into the right park light circuit. I'm using a 5a fuse, mostly because that's the smallest they had. I initially tapped into the fog light relay at the lower right post, as shown in the OP's pic. That didn't work, so I tapped into the lower left post (Pic 1 below). Upon verifying it worked, I used a small spade connector, and modified it to fit in between the adjacent fuse. See Pics 2-3 below.
So many thanks go to gooffeyguy for the detailed description and instructions. I may look into tapping into just the low beams, instead of the parking lights, as the fogs come on when I remote start it. I'm using
LED Switchback Fog Light Extremely Super Bright Dual Color 6000K Xenon White / 3000K Yellow Switch PS19W PS24WFF Fog Bulbs.

The lower left terminal on the relay is the one I said to tap into in the original post. It just looks like it's going to the lower right terminal in the pic.

The fog light as well as the low beam relays are both ground triggered so if you're feeding power into that socket where the fog light relay used to be, you're pulling power to run the fog lights from the park light circuit. Might be ok from the trailer park fuse but will most definitely cause issues if tapped into the left or right vehicle park fuse.

The way the add-a-fuse works is to pull that power from the feed side of a circuit, not from the fused side. You’ll be ok.
