I suspect this is a car you are asking about.

You are going to have to give us some CLUE as to what it is that you are working on.
My 1943 Supermarine Spitfire does not have a dimmer switch.............
If you don't have a wiring diagram or service manual, you can download many, for free, over at MyMopar

One will be hot when the headlight switch is pulled all the way out.
When another is jumpered to it the headlights will be on high beam or low beam, the other wire jumpered to the hot will cause the opposite.
As for the switch, one terminal will be common and the other two will be switched one at a time.
Connect the hot wire the the common and the other two to the other two terminals does not really matter which is which for these two.

I have this diagram but apparently when I blew it up I lost the bottom part of it just above the dimmer switch. Didn't notice till now. Thanks.
Another question. The dome light and the door light actuators have 2 wires . One hot, the other ground . Is the ground really nesessary ? Doesn't the mounting point act as a ground?

What is it that you are doing, IE chasing a problem or rewiring?
that circuit is simple. HL switch gets unfused power from the ammeter only for the headlights. Through and out the HL switch and to the dimmer. No matter which position the dimmer is in, two posts will be hot, with HL switch on, as it will be feeding either lo or hi
From there the lo or hi beam wires go out through the bulkhead connector, so more connectors that can be corroded. ANY connector, and ANY switch is suspect.
Then of course, around to the lights and two more connectors. Don't discount the headlights ground wire at the headlight area which can be trouble

Normally the interior light buttons are only a ground, but some have two wires, and still some cars only have one button with two wires.
Not positive, but I believe that second wire is so the twisting of the headlight switch grounds the interior light making it come on.
Normally the interior light always has 12v going to it and the door buttons and headlight switch only give the ground to make it light.
Del, @67Dart273 might shed more light on why the second wire is on the door buttons.
You are correct that the buttons get a ground through being installed in the metal body.
Mine are both a single wire and ground to the body. (73 Dart)

I am rewiring with a HOT ROD WIRE KIT . It's not that bad but a rock knows more about electrical than myself. You guys on here have been really helpful and between the CUSTOMER SERVICE and FABO I've been getting this done. There's more question on the way so...
