How To: Making your foglights stay on when turning your high beams on in your 94-04 V8 Mustang.

On all 94-04 GT & Cobra Mustangs, when the high beams are activated, the foglights immediately turn off. This is a function implemented from the factory. With the introduction of our Bi-Xenon HID Headlight Kit and HID Foglight Kit for 94-04 Mustangs, we wanted our customers to be able to run the HID high beam while having their HID foglights stay on. Outlined below are the steps necessary to have your foglights stay on when your high beams are activated in any 94-04 Mustang.


Materials Needed:

16 gauge wire approximately 2.5” in length ($4.24 for a 12’ roll)

Two male spade connectors ($3.14 for a pack of 4)

Electrical Tape ($2.09 for a roll)

Wire Strippers

Needle Nose Pliers

Preparing Jumper (fake relay):

Take your 16 gauge wire and strip off approximately ½” of the plastic sheathing on both ends.

Crimp the two male spade connectors at each end of your 16 gauge wire with your pliers. Wrap any exposed wire with black electrical tape.

This completes the fabrication of your jumper.

Step 1:

Open the cover on the fuse box located underneath the hood and remove the relay using needle nose pliers.


Step 2:

Once the relay is removed, you will notice five different open slots. The male connectors at each end of your jumper must be inserted in the two outermost slots.

Step 3:

Insert your jumper (fake relay) in the two outermost slots.

Step 4:

Finally, finish your installation by closing the cover on the fuse box. You are now done!

You should now be able to turn your high beams without having the foglights cut off.
