This thread’s purpose is to show the installation procedure for installing JDM fog lights. This came with: the assemblies, exterior and interior harnesses, relay, mounting hardware, and switch.
Tools Needed:
-Ratchet w/ metric sockets
-Flat Head Screwdriver (Long and Thin)
-Long Phillips Head
-Flashlight
-Electrical Tape
I will start on the interior side and then move to the exterior.
1. First disconnect the negative battery cable just to be on the safe side. Also make sure you have four mounting screws with nuts. Mine did not come with the nuts so I had to go and pick them up from the hardware store (M5-.8).
2. Remove your fuse box cover, plastic door sill, and plastic kick panel surrounding the fuse box. The door sill just pops off, so stick a flat head under it and pry it up. Then the kick panel can easily be removed.
3. Now pry off the switch holder. I used a long skinny flat head and put a shop towel over it so that I wouldn’t scratch up my dash. You will need to use some force as there are two clips per side holding the little bugger in there.
4. Disconnect the switches by unplugging the back of them.
5. Now decide which one you want to take out to replace with the JDM switch. I picked the cruise control since I removed it from the car. There are 2 small, gold Phillips head screws holding the switch in. Remove those and the switch should fall right out.
6. Install the JDM switch with the gold screws you just removed from the old switch. Plug the fog light harness in the switch (the only plug that will work) and run it down through the hole where the switch cover was.
7. Look under the dash where you removed the plastic panels, you will see a bunch of fuses and connection ports. Look for port #2 and port #5 (circled in red).
8. Now find the two brown plugs on the fog light harness. The plug with the two red wires goes into port #2 and the plug with the white/brown wire goes into port #5. Make sure they click into place so that you have a good connection.
9. Find the orange wire that is sticking out of the fog light harness. Now look all the way in the corner next to the firewall and you should see some wires wrapped in tape. Look for an orange wire in there and plug it into the orange wire on your harness.
10. Last thing is the relay. The bottom bolt on the hood release is used to mount the relay and the ground wire that is left. Bolt those things up and plug the harness plug into the relay.
11. Plug your switches back in and reinstall the switch cover by just pressing it back into place.
Ooooo it’s so pretty. Ok you are done on the interior side.
12. Remove your turn signals. There should be a Phillips head screw inside the bumper, look through the notch in your bumper to see the screw. After you remove the screw, they should come right out. Also pop out the black plastic piece below your turn signals.
13. Take out your exterior wire harness and run it down the inside of the bumper and make sure that the orange connector is on the drivers side.
14. Look behind the bumper where your turn signal used to sit and you should see a group of wires wrapped in blue tape. Remove the tape and connect the orange connector from the harness to this orange wire. I also wrapped mine in electrical tape just to be on the safe side.
15. Take out your ground bolt. Look in the center of the car, right in front of the radiator will be a frame piece that a metal line hooks onto. There are two holes under that line. Use the bottom one (circled in red) to bolt your ground to. You can either sand the paint off of that area or just stick the wire prong between the bolt head and washer to get ground, that’s what I did and I had no problems.
16. Now get out your JDM fogs and plug them in. The orange wire of the plug should point towards the center of the car, or if you did the H3C conversion, like I did, than you will plug the ground wire into the black wire.
17. This is a good time to make sure everything is connected properly. Hook your negative cable back up, lay the foglights in the bumper, and switch your parking lights or headlights on and push the button. Taa-daa.
18. OK, you’re almost there. Make sure the housings are sitting in the right spot, they should fall right into place. Each side uses two screws. Put the screw through the mounting hole and hold it with a phillps head while you tighten the nut on the back with a wrench. This is a tricky process so you will just have to do it the way that works best for you. If you have large hands than it would prolly be easier to just take the bumper off.
19. This is a good time to adjust those bad boys. Turn them back on and make sure they line up by parking in front of a wall. Tighten the adjuster screw (the one with the spring on it) to point the foglight up or loosen it to lower the foglight.
20. Reinstall your turn signals and you are done.
The entire process took me two hours I think, bc I took my time and didn’t rush it.
Let me know if you have any questions or need more detailed info. Thanks for reading.
