can we have a little bit more detail with the wires. Please!
I took a look at the wiring and got the colors, at least the colors from my car. Always test wiring before making any modifications. This is just meant as a general guide. Everything can be done in the fusebox on the driver's side under the hood. Open hood. Remove cover to fuse box. Once you remove cover, locate foglight relay and taillight relay according to the cover. Standing in front of the car, the foglight relay should be closest to the strut tower in the middle, and the taillight relay should be along the right side at the top of the row of 3 or 4 relays. Before disconnecting the battery turn the foglights on and off and you should be able to hear and feel the relay clicking. Same for the taillight relay. After confirming you are using the correct relays, you can disconnect the battery.
From there you will need to remove the fuse/relay panel. You can see small black clips within the white tray sealing the fuse block. Work your way around the block separating these tabs. Just push the black in toward the fuse block to release. There is one, right next to the battery, which moves the opposite direction. This is the hardest part of the process, but just be patient and keep working the block up gradually. It may be easier if you disconnect the blue harness plug that is connected in the center of the block also. Just pull up on the white handle and it should separate.
After you get the block up so you can see all the wiring, you'll need to temporarily connect power again so you can test your wires. Locate the foglight relay, (make sure your foglights are off), and test for the wire that gets power when the headlights are turned on. Mine was Grey with Blue stripe. When you find the correct wire, mark it. Now to the taillight relay. Test for the wire that gives power out to the taillights when the switch is turned on. Mine was Grey with Black stripe. You need to strip a little insulation from that grey/black wire and connect a scrap piece of wire about 6 inches long. Properly insulate the connection.
Now cut the grey/blue wire about 2 inches from the foglight relay. The end going into the harness can be capped off. The end coming out of the relay needs to be connected to the scrap piece of wire we had connected to the taillight relay. Now test everything. You should be able to turn your foglights on with only the parking lights being on. If everything works properly, make sure all your connections are secure and well insulated, and put it back together the reverse of disassembly.
Long write up, but it really wasn't that difficult if you have some basic electrical skills. But, if you don't feel comfortable doing it, then seek out a qualified technician. Hopefully someone at a car stereo shop/alarm shop will be able to take care of it. That is my background from way back.
