They'll turn on and off with the Parking Lights. They'll turn on and off with the Ignition KeyĢ) You can tap into the Green Parking Light wire. Easiest, safest methods:ġ) You can tap into the Black-Orange wire, which is the main fan power wire. You can change it around based on how you want the fog lights to turn on. Pin 86: This is the wire which will turn the fog lights on or off. You can either have two wires coming off Pin 30 (one for each fog light), you can run two relays wired up the same way (one per fog light) or you can look for the hard to find SPST relay with two Pin87's vs one Pin 87 and one Pin 87a. Pin 30: run a wire from here to the foglights. Pin 87: Run a fused wire from the battery to the relay. I'm going to pull eckoman_pdx's post from here: That's it! Two simple steps and enjoy your fog lights whenever you want!!! Wiring is done in the same way in the 93-95 diagram (color) #Easiestsimplestwaytoindepednentlywireyourfoglight s Mine are wired as I instructed in the two steps above for the ultimate fog light freedom.īasically what I'm saying to do is make the relay and switch Canadian style in the 91-92 diagram (black and white diagram) at the switch and relay while leaving the G/Y wire between the two components wired U.S. your door lights so that your fog lights only have the capability of turning on when the door is open.now that would be silly. You can run it to your parking light circuit if you're concerned about forgetting to turn them off via the switch when leaving the car. You have the option to run this wire to whatever circuit you chose. If you have a White/Black wire for the switch ground it is not shown to be controlled in the diagram.Ĭoncerning the Red/Yellow wire from your relay. By grounding it directly you have voided this. Similarly, the ground wire (Red/Black (M/T) or Red/Yellow (A/T)) from the fog switch is a controlled ground. By splicing it to the Red/Black wire you're giving it power whenever the key is on. Why this works: The Red/Yellow wire on the fog light relay is a controlled power source from the headlight system and turns on when the headlights do. If you have the White/Black wire coming from your dash harness to the fog switch then you may not have a controlled ground but will have to ground it directly to the chassis if step one doesn't work by itself. Ground it to the chassis from the switch like I did here (never mind all the unfamiliar wires as they are for motorized fogs. If you have a Red/Black (M/T) or Red/Yellow (A/T) wire going to your fog light switch then this is the controlled ground that we don't like. Ground the fog light switch ground to the chassis. It will have voltage when you turn on your head lights. Cut the Red/Yellow wire to splice it in with the Red/Black as shown here: ()ĬAUTION:Make sure to cap off the other end of the now unused Red/Yellow wire.
In the frunk (front trunk) access the fuse panel and underneath the fog light relay there are four wires (Red, Red/Yellow, Red/Black, and Green/Yellow).

I have reviewed other threads about how to accomplish this but I think it can be done much easier. Therefore in ALL cases the accessory MUST be wired through a fused relay.Tired of your fog lights turning off when you hit the HI-beams or when you turn your lights off? Well I figured out how to run the fog lights independently. The switch is an electronic switch rated at 3 amp’s. Lower light can be wired to separate dash light circuit.Upper light is ON when the switch is pressed IN.Single Pole Single Throw ON-OFF Push switch.
