Is there an (easy) way to bypass the automatic headlight sensor? Im in the military, and when going on base, its courtious to the guards to turn your headlights off when approaching at night. Im just wondering if there is a way to manually turn my headlights off when its dark. Thanks

I haven't investigated this at all but there must be a switch on the e-brake handle.
Seems like you could extend that to another switch wired in parallel that you could turn on / off whenever you wanted lights out while using the auto sensor.

The real fix is as mentioned above though. Disassemble the dash where the sensor is and wire in a resistor. Then, you should have DRL's and manual headlights.
One other option is to find the plug in the wiring harness behind the radio and disconnect it. The issue with doing this is, it disables the sensor along with the e-brake switch. That means the car won't know when the e-brake is engaged (no red "BRAKE" light on the dash) and it may affect when you can open your trunk (manual can only open when car is off and auto only when in Park). I'm not sure what other sensors use this plug either...
EDIT** An afterthought....if you can determine which wires go to the sensor, you might be able to access them by pulling the radio instead of tearing up the dash.

I have never used my headlight switch since 2002.
As soon as I release the brake the lights come on. When I put the brake back on, they go out.
Seems like a momentary contact switch would do the same thing as the brake handle but like I said, I haven't checked it out. I was just guessing.
You're saying the ignition has to interupt after they come on once and you are right I'm sure. I never even noticed. Thanks.

ok hows this ---- leave in your sensor and in addition wire in a simple toggle switch in (open\close)...wire in one side to 'a-1137' and the other to 'b-1137'..what that do well now you have a manual override...close the connection auto lights disabled... open the connection auto lights controlled via sensor...reference this link http://www.xse.com/leres/ss/images/drl-s2-sm.html my job is done

Looking at the diagrams, I'd expect it to be something like this:
Pop off the trim and unscrew the 7mm bolts holing the radio in.
Carefully remove radio (may have to unplug wires on back).
Grab the smaller, blue connector on the right side of the DRL box.
Make the connection to the wires in G and H (should be light green/black and yellow/black wires).
Button up in reverse order and you're good to go.
