Jumper power to these fuses in the fuse panel and see if she will start.

Yep - that's the bypass you need. Nice diagram, buddy.

Thanks Buddy . Having that info will add a measure of confidence to driving the old girl.

There may be some other things needed to make it drive right, like a fuse for the tranny. Pretty much any fuse that gets power from the igntion you could tap in a bypass with these tap a fuse things. I'll have to look that stuff up and add a note on the drawings, but if bypassing those on the drawing now gets you an SES and WTS light back then you know you have a break in the wiring, likely the ignition switch itself.

update....... I bought a new ignition switch and the truck fired right up with all dash lights working properly.

I have been meaning to add these since i replaced the switch a while ago. I noticed the purple wire melted a tad bit. Can anyone tell me what the purple wire does? Has anyone else had this melting issue when their switch went?

Be sure you have voltage at the LH battery.

The RH battery supplies power to the starter and the LH one supplies the chassis.

A bad ground cable on the LH battery can cause whats happening.

Check tha main fuses in the junction box on the LH fender under the hood too.

This sounds like a broken connection of some sort.

My first place to look though is the LH battery ground, both at the battery and the engine block.

FWIW if you decide to swap out the steering column, the first 9 steps from this "how to" should help

I found changing ignition switch wasent to hard at all

When the ignition switch contacts get burnt it takes more current to pass through the higher resistance,and that is what usually causes the melting in the harness.
