Look in the lower right corner of this diagram.

There is a black/lightgreen that goes from the ignition switch to the wiper module.
If you look at this diagram.

You will see in the upper left corner that the lights are fed by a black with a orange stripe.

That helps some, the wire that fried is a small blk/green strip it goes to where 2 large blk/green strips are connected by a factory junction they all loop off the piglet that goes to the head light switch. I guess i need to drop the steering column case we can't get to where the fried one goes into the large coil of wiring harness wires.

heres what i got big black wire with green stripe coming out of ignition switch runs together with another big black wire with a green stripe then they go into one small black wire with green stripe then runs into small black box with 6 wires has a red,white, black with green stripe, black with pink stripe, and 2 other colors then they run straight through the black thing and go into the internal windshield wiper washer switch, my question is what could have cause this wire to fry like this??? i found another wire that was burnt to the wire in one part...can i just run a new wire for the black with grren stripe?? or do i need to run new wire for it and buy a new switch that controls the diff setting? the switch went bad about 10 years ago and only had one setting switch...so could that have finally gave out and burnt the hole wire?

Well, if you look at the diagram, it sounds like those wire colors do match the wiper system wires. Do the wipers work? And I would also get out under the hood and check the wiring around the wiper motor. And also the wiring where it goes through the firewall. I am surprised the wire smoked, instead of blowing the fusible link over at the passenger side fender/starter relay + post. Maybe someone cut the fusible link out and didn't put it back.
If you are afraid of smoking wires again, and want to test it first, disconnect the battery and put a battery charger on the + cable and the - cable. The charger should have enough oomph to run your accessories, but it has a self-resetting circuit breaker in it if things try to smoke again.
