[img]/wwwthreads_images/icons/smile.gif[/img] That little brown wire is to '"tickle" the alternator and get it charging. It stays connected to the red lead. Or....if you want to get fancy, you can run a lead from the ign switch to a light bulb then to that brown lead and on to the alternator. that way, when you turn on the ignition, the light "bub" will light up till the alternator starts charging. Your own little idiot light.[img]/wwwthreads_images/icons/crazy.gif[/img]

I never believe any statistics unless my moonguys [img]/wwwthreads_images/icons/crazy.gif[/img][img]/wwwthreads_images/icons/wink.gif[/img] made 'em up themselves.

Re: DUI-hei help

Dave is correct.
If you are standing behind your alternator, and the wire connects to the left (#1) terminal on the two wire plug, then it is the one that should be used for the 'idiot' light.
You will need to get a bulb holder that has two wires, and doesn't ground through the housing.
Connect the 'Thin brown' wire to one side, and a wire from the 'Heavy Red' to the other.
The light should go out when the alternator starts charging and when the key is turned off.
When the key is 'ON' but the engine is not running, the 'Idiot' light should be on.
It should also light up when the if the alternator fails.

If you don't mind, would you tell us how much you paid for that DUI ignition set up?

Good luck, Aaron.

If a tree falls in the forrest, and there is no woman around to hear it, is the man still wrong?
