one end with the fuse goes to the battery, it comes around the front end of the car hooks up to the passenger fog, continues on and hooks up too drivers fog and you will find a ground right there. attach it, continue on and route the cables inside the car. install the switch and plug the harness into that, from there you should be left with i think a ground, 1 red wire it think, and a plug that plugs into the fuse box. plug red wire from switch to red wire coming from fog harness, attach ground accordingly and and plug the leftover plug into the fuse box. i think its socket 1 or 3... not sure, experiment because one is constant power, another ignition activated, and the others are duds.

after everything is in and battery connected, press the fog light button. if they come on unplug the plug from fusebox and place in a different socket. then try again with the key OUT of the ignition. if they dont come on with the button pressed then turn they key, they should come on then.... well thats it i think


this is a writeup for 92-95 civic fog lights, it may be the same for others im not sure. but this is from my experience
