On the Track/Kick the knob is not the switch,
the switch is in the plastic combination assembly
in the middle of the steering collum, it all comes
apart, and if you pay attention you might even get it
back together again   .  I've had mine apart a few
times to fix this or that, the first time my wife was
driving and smoke came out of the steering collum,
I'm thinking the whole thing is fried, but I just fixed
it and put it back together, works fine, and has for years.

i have never hade to fix the one on my kick, but it's  the same as my nissan that i used to have, the turn signal and high beams didn't work just had to clean the contacts

If for some reason I cannot get around to taking it out and apart tonight, which wire can I run a toggle switch to as a jiffy rigged way, to get me back to work early tomorrow morning with headlights.

The power for the headlights goes from battery/alternator to the fuses (one for each) to the headlights, then a red wire with white traces goes from each healight, they join and go to the switch.  The switch is more complicated than a toggle but if you tap into the red/white wire and run through a toggle switch to ground, it will turn on your headlights.

It will leave your low beams on regardless of the dimmer switch position (if the dimmer is to high beams, both high and low will stay on.

Each headlamp has a 10amp fuse so you need to use a switch rated for at least 12VDC/20 amps.  You should also use 12 guage wire or larger (size, not number) and it should be a temporary band aid.  Make sure you run it to a good ground.
