How to rewire the fogs to come on without the headlights

The fogs can easily be rewired to allow them to be run without the headlights. The fog light switch on the turn signal stalk still continues to turn the fogs off and on as before - the only difference is the fogs can be turned on without the headlights. This is a especially great mod for those with DDE's. The best part: This mod is nearly free.

Please note: While the fogs still shut off when the high beams are turned on (in accordance with various state laws), in some states it's illegal to have fogs on without headlights and could cause you to fail inspection. Be sure to check your local laws before proceeding.

  • Quick tap (can be purchased from Radioshack)

6. Cut the fog light wire around 3 inches from the base of the relay.

The '02-'03 wire:

'00-'01: Cut the yellow wire with two silver horizontal lines on it coming out of the fog relay. Check the fuse box cover to confirm you're looking at the fog light wire coming out of the fog light relay.


Cover the end of the fog wire running down into the car with electrical tape and tuck it away:

8. Strip the fog light wire that is coming out of the relay (the wire found in step #6)

Use quick splice to splice the fog wire you just stripped to the taillight wire (red with green stripe and silver spots):

Quick splice installed:

10. Turn on parking lights and fogs. Fogs should come on with your parking lights! If not, check your splice and wiring.

Reassemble the fuse box. The finished product:
