Thought I would share with you on how I added the OEM fogs to my G6. I previously had a thread asking if anyone has done this. Seeing no one responded that they have, I decided to try it out. I suggest having someone help you with the install to save time. Also, if you don’t know much about wiring and electrical work, please avoid this mod. I don’t explain everything in this how-to, some of the electrical work is implied.
First off, the idea:
Because I live near the water, fog is something I have been dealing with my whole life. Not some light stuff, but stuff so thick you need to alter your route to save time. When I bought the car I knew that fog lights were a must, and not just for looks. I first and foremost wanted to have the OEM fogs installed. This defiantly made it tough because the G6 doesn’t have any wiring for the fogs when they weren’t bought as the option. After some planning, I came up with the circuit below.
The Circuit:
For those of you who understand schematics this should be easy to follow. For those who do not, well here is what the circuit does:
When the parking lamps are on, your switch will turn the fog lights on or off, simple as that.
I designed the circuit this way so I won’t forget to shut the fog lights off. The way I have everything powered, it is impossible to leave them on with the car being off. When the parking lamps are on, it energizes the relay and closes the switch in the relay. The other circuit is the power (Using “add-a-circuit” which is placed in the Emissions fuse spot) to the fogs to the switch (Mounted in the dash) to ground (Chassis of the car).
The Parts I used:
First, you need the OEM Fogs, I bought mine off Ebay for about $100. Also a switch (SPDT), some wire (I used 16 gauge wire), the “add-a-circuit” thing, spare fuses, and butt connectors. Not shown: The power plugs for the H11 fog light bulbs, the relay, the tubing I ended up buying to protect the wires, electrical tape, zip ties, and quick connect wire connectors (to connect to the wire to the relay and the switch. Also two were used to be able to remove the left-front light easy out of the circuit.). Most of these items can be found at a store like Consumer Auto Parts. The power plugs for the fogs most likely need to come from a junk yard. I got mine from a mechanic who ripped them out of an old car for me.
The How-To:
First you need to install the fogs and run the power for them. Cut out the grills where the fog lights go, I used a pair of wire cutters and a knife. Next, to run the wires you need to remove your headlight units. For instructions for this, consult your owner manual. For every wire I ran, I first measured out how long the protective plastic tubing would be. Then I ran the wires through the tubing and fed then through the car. Looking at the front of the car, I installed the left fog first, measured the tubing to go from this fog to the right fog light, ran the wires through the tubing, ran the wires/tubing through the front of the car, and zip tied the tubing secure to the car. I then plugged in the power plug to the light and terminated it to the wires I just ran. Note: Follow the tubing that already has been run through the front of your car.
Next I installed the right fog light, and plugged in the power plug to it. Following the schematic I connected the ground wire to the ground of the left fog, and the power wire to the power wire of the left fog. REMEMBER: you need to be able to connect another wire to each of the wires. When I used the butt connectors I put two wires in one side and the third wire in the other.
Next I ran a ground wire from inside the car, through the firewall, into the engine area. I left the spool inside the car and pulled the length I needed through the car before cutting the wire. Inside the car this wire needs to run to the spot you are mounting your switch, with some slack of course. This wire is the same ground wire in the next step.
Next I measured out a tube to run from the right fog, up the right side of the car, to the windshield side of the battery. I ran two positive wires and one ground wire (Previous step) through this tube and installed it into the car. Make sure to mark which power wire is which. One will be used to power the lights, and the other to go from the relay to the parking lamps. Connect the one that will power the lights to the positive of the fog lights.
Next is the mod for the parking lamps. The picture might explain it better, but what I did was break the wire that supplies the power to the parking lamps (side markers), and “T” in a wire off of these to go to the relay. When I cut the wire, I put these two ends into one side of a butt connector, the other side of the connector goes to a wire, through what I call quick connectors (so if I need to remove the headlamp assembly I and quickly undo this wire), and to the wire that leads to the relay. Connect the wire from the quick connects to the wire that will go to the relay.
Next mount your relay. I did mine on the plastic shell over my awesome 4 liter engine .
I then mounted a ground wire to the car (where-ever) and ran this wire to one side of the coil on the relay.
Next I took the wire that went to the parking lamps and made the other side of it go to the other pin to the coil on the relay. When the parking lamps are on, the coil will now energize and close the relay’s built in switch switch.
Next I used the add-a-circuit product. I placed two fuses into the holders and placed it into the slot that the Emissions fuse went. This adds a wire to the car to supply power to whatever. I then connected a power wire to this and ran it to one side of the relay’s built in switch. I had to customize the fuse box’s cover to make sure the wire didn’t get pinched.
Next I took the wire that goes to the positive side of the fog lights and make it go to the other side of the relay’s built in switch. Now the relay can turn on and off, and the switch side of the relay supplies power from the fuse box to the positive side of the fog lights.
Now we can venture into the car to finish up the job. Next you need to mount your switch. Find a spot where the switch will have plenty of clearance behind it. Cut out the spot and mount the switch.
Next you need to check which way the switch closes when it is in which position. If the switch says “ON” on the part you will see, put the switch in this position and see which poles close you want the ground wire in the next step to be the outside pole of the ones that have shorted.
Next use a quick-connect connector to connect the ground wire that was run through the firewall to one side of the switch (outside pole).
Next I ran a wire from a place I grounded it (under the center console, See picture), to where I mounted the switch. This wire goes into one side of a butt connector; the other side goes to two wires. Place quick connectors on these and attach these to the two remaining places on the switch (middle pole and outside pole).
Next turn your car on and test them out. By turning your headlights on you should hear the relay close when you are standing outside the car with the hood open. That means this part of the circuit works. Now turn you’re your fogs on and see if they turn on. If either don’t work, and the car and headlights are on, then something is wrong and you need to do some troubleshooting.
Pictures:
Please do some research and poke around with your car before trying this How-To out. Make notes on what is the easiest way to complete this.
If anyone finds anything wrong with this mod, please message me on it, and I will make the change. Also, if something isn’t clear, ask me about it.
