Adi Posted March 7, 2003 Report Share Posted March 7, 2003 This mod is for 86-89's I'm not sure if the wiring is the same on earlier models. It allows the use of your foglights with parking lights ONLY, you no longer have to have the head lights on in order to have your fog lights I know there are people that would like to do this and can't for one reason or another. Â The ONLY reason this should not work on 86-89 LE, ES, TSi, or ESi-R's is because someoen previously dorked with your wiring. 1. Gather the necassary tools. Philips head screw driver, wire crimper, electrical tape aka black tape, and a small 10-12 " peice of stranded wire. Since you are using this only as a signal wire to the relay it can be a pretty small wire. 2. Locate the foglight relay; it is located on the passenger side of the car in front of the air can right underneth the horn and two other relays. I found it MUCH easier when I removed the turbo to i/c pipe. 3. Locate the 10 gauge green wire. Â Cut the wire where it enters the harness to the rest of the car. Â This should leave you with lotsa wire to work with. Second, strip abotu 1/2" back on the wire or a little less depends on how you plan on attaching the upcoming wire. 4. Pull the passenger side marker light out. Â This requires a phillips head screwdriver to remove two screws. Â One on the marker light itself and one in the far bottom (pass side) corner. Pull the light out. Â To make it a bit eaiser you can actually pull the light out of the marker housing. Â There are two wires here. Â A green/white and a black. 5. Pulling the light out enough to reach the wires easily. Â Take the G/W wire and you can do several different things. I myself carefully cut a ring in the sheath, and pulled back the insulation on each side. Thsi exposed abotu 1/4"-1/2" of wire that was unmolested. Â Take the peice of stranded wire strip about 1/2" and wrap it around the bare wire you just exposed on the G/W wire. Â Tape the splice you just made. Â (You can also solder it to make it a better connection. Â Also you can cut the wire strip both ends of the G/W wire and tie it all together with a wire nut or somethign. Â IMHO The way I did it didn't take very long Was easier to do to then fighting with gettign the stripper in far enough to strip the back wire. 6. Run the peice of wire you just tapped into the G/W wire through two hole on the inside of the fender. 7. splice the wire you just ran through the fender to the green wire that you stripped. Â Make a nice secure connection tape it. 8. Install the lights and grill back into place. Â Watch in amazement. Â Looks GREAT!!!!!!!!

NeedAStarQuest Posted March 7, 2003 Report Share Posted March 7, 2003 Since you are cutting the relay, how is the power handling been? I know if you rip relays out where they were supposed to be you sometimes burn up the bulbs and wiring..had any problems? Josh Link to comment Share on other sites More sharing options...
Adi Posted March 10, 2003 Author Report Share Posted March 10, 2003 Nope. If you know how to read elec diagrams. You see that the green wire your cutting is a signal wire only. All it does is send a +12v signal to the relay to turn on the relay. The main power flow through the relay is throuh the red wire adn the red/white wire. I've been runnign my lights everytime I start my car since I did this mod. And I havn't had a shred of a problem yet. Link to comment Share on other sites More sharing options...
Jonathan Posted March 10, 2003 Report Share Posted March 10, 2003 Thanks for the right up. Link to comment Share on other sites More sharing options...
CHC Posted March 24, 2003 Report Share Posted March 24, 2003 why not wire the "power on" or voltage sensing prong on the relay to the radio "memory" wire, and then wire that through the dash switch? then you can run the lights whenever you wanted to?

starquestPilot Posted April 30, 2003 Report Share Posted April 30, 2003 There's an easier way to wire them so they work anytime. Takes about 10 minutes... 1) Cut the green wire about 1.5 inches from the relay 2) Splice the short green wire (from the relay) into the red wire. I used one of those in-line splices for 14-16 ga wires 3) Cap the green wire going into the harness Now, the fog lights work anytime the fog light button is pressed - so don't forget to turn them off. You won't get a "lights-still-on" buzzer... (Works on my '87 LE) Link to comment Share on other sites More sharing options...
