Ok I figured it out. This is the "non-hacking you can go back to stock" version.

After carefully reverse engineering, testing, and verifying. I figured out a way to disable the DRL’s and to have the fog lights on without the headlights.

If you don’t want to read a long winded explanation of how and why I did the mod skip to the procedure.

For the fog lights to work independently from the headlights you need to separate the switch from the DRL module, and supply power to the fog light relay from the parking lights. Why from the parking lights? So you don’t forget that you have them turned on.

There was no real easy way to eliminate the DRL module completely without some major hacking. Also it’s a good thing to have on the car and my way makes it for easy reversal of the mod. Since I’m not eliminating the DRL module I decided to have a switch to just turn the DRL’s off. I’ve heard of people driving around with the e-brake up one notch to turn off the DRL’s. That’s not a good thing, for one you will wear out the rear brake pads prematurely and secondly you have the brake warning light on the dashboard. This light tells you if you have a problem with your braking system. So having it on all the time is not good either. So I looked into the electronics of the DRL module. Basically the e-brake and the low brake fluid warning switches are connected to each other via the DRL module.

I took some pics as I went along but most came out crappy. I posted them up on Yahoo. HERE

Also I have 2 schematics I made but they are in pdf format and I don’t have anywhere to host them except for here.

NOTE: The wire colors are "solid color/stripe" if there is one color then there is no stripe.

1. Find the Fog Light relay. Located in the drivers side foot well. Look up.
2. Using the 10mm deep socket unbolt the two bolts holding on the DRL, FOG light and other stuff up there.
3. On the FOG LIGHT RELAY cut RED wire about 2” from connector.
4. Crimp a male butt connector on the connector side, and crimp a female butt connector on the harness side.
5. Take a length of wire about 3’ and crimp a female butt connector on one end.
6. Plug the new wire into the RED wire you just cut with the male connector on it.
7. Label the free end of this wire as FOG LIGHT RELAY.

8. Find the DRL module. Again located in the drivers side foot well. Look up.
9. Unplug the 2 harnesses. You only need to modify the small harness with 7 wires in it.
10. Cut the YELLOW/GREEN wire about 2” from the connector.
11. Crimp a male butt connector on the connector side, and crimp a female butt connector on the harness side.
12. Cut the BLUE/ORANGE wire about 2” from the connector.
13. Crimp a female butt connector on the connector side, and crimp a male butt connector on the harness side.
14. Plug wire YELLOW/GREEN into wire BLUE/ORANGE on the harness side.
15. Take another length of wire about 3’ and crimp a female butt connector on one end.
16. Plug the new wire into wire YELLOW/GREEN on the connector side.
17. Label free end of this wire as DRL OFF.
18. Run both wires up the wire harness and secure with tie wraps.

19. Remove the cover on the side of the dashboard to expose fog light switch.
20. Run the free wires along the harness and into the area of the foglight switch. Use tie wraps to secure.
21. Find a suitable location for the SPST switch. ( I used the empty switch plate)
22. Terminate the free wire labeled DRL OFF to one side of the switch.
23. Terminate another length of wire to the other side of the switch.
24. Label this new wire as GROUND.

25. Unplug the fog light switch harness.
26. Cut RED/WHITE wire about 2” from connector.
27. Crimp a male butt connector on the connector side, and crimp a female butt connector on the harness side. (ignore my picture I put the connectors on the wrong side)
28. Take a length of wire about 1’ and crimp a female butt connector on one end.
29. Label the other end GROUND.
30. Connect the new wire to the connector side. Leave the other end free for now.
31. Splice the wire labeled FOG LIGHT RELAY into the LIGHT GREEN/BLACK wire.

32. Find a good ground location.
33. Take both free wires labeled GROUND and terminate them with a ring lug.
34. Remove the bolt. Put the ring lug over the stud. Fasten the bolt back on.
35. Double check all connections are solid.
36. Plug the harnesses back into the switches.

 

What do you do with the BLUE/ORANGE wire from the DRL module on the connector side,
RED wire from Fog Light Module on the harness side, and the RED/WHITE wire from the Fog Light Switch on the harness side?
