super easy my friend. u will need:a 20 amp fuse, wire and a relay.
step 1- dissconnect your fog lamps from the car .
step 2- cut the plug off of the factory wires and tape them off. u wont use these anymore. that plug put back into the bulb.
step 3- find out which one is pos and neg[ red + , black is ground]on the bulb.
step 4- the relay you need to get is a uneversal 5 pin relay. any part store will have them. i want u to wire the relay like this
30- this will go to the batterys pos [+] side. u need to put a 20amp fuse no more than 3 inches from your battery connection.
87a- nothing leave it alone.
87- this will be where u hook the pos[+] side of your for lights to
86- ground. u can put this to the battery neg.[-] side
85- connect this wire to a parking light or headlight wire that has pos[+] 12v. if u hook this up to your parking or sidemarker lights, the fogs will come on with them. If u choose to hook it up to the headlamps, they wont come on till the headlights are on.
last dont forget to ground ur fog lamps. that should be the other wire in the plug for those foglights at the bulb itself. u can take it to the batterys ground[-] side. just make that wire short as possible.
