Finally Wiring Up My GT/CS Fog Lights - Need some help (relays)

[DirtyD]

So hopefully this weekend, weather pending, I will finally get around to wiring up my GT/CS fog lights on my 2013 that I installed over a year ago. :burn:

With that said, I have the idea on how I was to wire everything up, but I'm in need of a little help getting everything layed out correctly with the relays.

Overview of how I want the setup to function:

1) Grill lights will turn on at the same time as the LED DRL strips in the headlights.
2) Grill lights will then remain on with headlights turned on (both manually and Auto mode), and also stay illuminated when high beams are engaged.
3) When the MFS (multifunction switch) is pulled out to turn on the GT/CS fog lights, I want the grill lights to switch off and the fog lights to now illuminate.
4) When high beams are engaged WHILE fog lights are on, I want the GT/CS fog lights to shut off as fog light due when the high beams are engaged, and I want grill lights to illuminate again, taking their place.

The GT/CS fog lights will be tied into the existing fog light circuit

I figured out that I will only need 1 relay, a 5 pin ISO style for each circuit afterall. All negative leads will go to a chassis ground as well.

Here is what I came up with using as far as the diagram goes. Does anyone think I will have a problem using the "+" wire from the DLR strips as my constant power wire?

Going for the Baja truck look Derek?

Why not just get rid of the stockers and use the GT/CS lights? I'm sure you could get a good chunk of change from the stock center fogs. I'm far from an electrician so I can't really help ya here though

I say down with my SAE mechanic friend this weekend after 2 days of yard work and we figured out a plan.

I'm keeping the grill lights because I like the nostalgia look

Wired mine up to come on with running lights. I love the look.

Michael, can you show me a diagram? How did you tie into the running light system? Because that's basically how/when I want the grill lights to come on.

Honestly man you would not like way I wired mine. I didnt use relays or anything. I have no issues and use my lights for several hours at a time. I tapped into the running light wires going to the fender lights.

Fender lights as in the "reflectors"? That's not a bad idea. I've been trying to think of a way to get around the shut off for the DRL LEDs when the blinker is on.

I'm still interested in a diagram or something. Just for thought.

Yea I just tapped into side marker lights. I didnt use a diagram just found my hot and tapped into then same for ground.

This was for the grill lights, right?

Do the side markers come on when the DRLs come on?

[Rebelracer568]

No these are for my cs lights in the front bumpers

Damn. Feeding the halogen bulb off the sidemarker lights? LOL

I'll probably feed the grill LEDs off those or something. My GT/CS fogs will get tied into the existing fog light circuit.

Haha yea like I said prob not best idea but it works and have no issues.
