The reasons I wanted to accomplish these mods are:
- I upgraded to LED headlight bulbs. The DRL uses the high beam bulbs at a lower voltage. LED bulbs do not do well at less than designed voltage. Although they are dimmer, there was a pronounced flicker when in DRL mode.
- I wanted to disable the auto headlights.
- I wanted independent control of the FOG lights when the headlight switch was in the park lights or headlights position. I also wanted the FOG lights to stay on in the headlight high beam mode.
To disable the DRL & auto headlights: Cut the #12 BLUE wire and insulate both ends. Alternately, you can remove the socket and wire together from the connector. I had difficulty releasing it without the proper tool. So I cut the wire instead of risking that I damage the connector or socket. It could be re-soldered or connected with a Posi-Lock connector to restore normal function.
To accomplish the FOG light mod: Install a jumper between the #4 WHITE wire and the #14 LT. BLUE wires. I used Posi-Tap connectors which are very reliable and secure. They are also easily removed and reused.
If you want/need the ability to easily or temporarily restore normal function, ON/OFF switches could be installed inline with the #12 BLUE wire, and separately inline the jumper for the FOG lights.
