This Simple Mod is to allow fog lamps to run with high beams on or off. I am sure there may have been earlier posts, but thought I would share anyways. I know this works on 99 Rangers and probably any other Ranger with a "Fog Lamp Isolation Relay". 10 cents worth of parts and you are good to go. Just Remove the isolation relay, add the jumper, and fog lights will come on when the Parking Lamps are on and the Fog Light switch is depressed. Save the relay because it is the same as the actual fog lamp relay.
