Do you have access to a voltmeter?  If so, connect it between ground and the

`cigar' fuse.  Turn the ignition on and off.  If you get ~12v w/ the ignition

on, and 0v w/ the ignition off, then you've found your ignition controlled

circuit.  According to my '96 schematic book, this _should_ be the case.

 Your white light minder wire connects here.



You now need a circuit that's hot when the lights are on.  Gain access to the

red and black wire that goes to the dimmer for the I.P. lights.  (You can

disconnect the connector from the dimmer when you do this test, it will still

turn out ok.)  Connect your voltmeter between the red/black wire and ground.

 Turn the lights on & off.  Again, you should see +12v when the lights are

on, and 0v when the lights are off.  Connect the red wire from the light

minder here, and from what I can see, it _SHOULD_ work.  



Maybe I have the light minder wires backwards?
