MODIFICATION MADE TO FOG LAMP SWITCH
1. Remove the fog lamp button on the dash, using a thin flat screwdriver or butter knife. Note the wires connected to the back, they should correspond to the original list of colors and functions above. 2. Cut the 3rd wire from the top (power from head lamps), leaving about 2 inches from the back of the fog light switch. The cut wire coming from inside the dash (power from head lamps) should be taped, covered, or capped some how, as not to allow the metal tip to touch any thing causing a short. This wire becomes live when the head lamps are on. 3. Now cut the 1st wire (power from the parking/dash lamps) again leaving about 2 inches from the back of the fog light switch. Be careful the wire coming from inside the dash is live when the parking/dash lights are on, so keep the lights off and/or cover it temporarily once cut. 4. The cut 1st and 3rd wire attached to the fog light switch need to be stripped about ½ an inch from the cut tip. 5. Now the 1st. wire coming from inside the dash (power from parking/dash lamps) needs to be stripped and spliced to attach to the 1st wire still attached to the fog light button and also to the 3rd wire still attached to the fog light button (originally power from head lamps). 6. Once the 3 wires are spliced together, tape them up or cap them, and check for proper operation. Check all combination of parking lamps, fog lamps, head lamps, and high beams. 7. If everything checks out and works properly just pop the fog lamp switch back into the dash and enjoy.
***Note the only tape that should be used is insulated electrical tape.***
