Shifter Wire Fix
If you are blowing a fuse and your throttle and gauges quit when you move your shifter, this will help. As these trucks get older, the movement of the shifter causes the wires that run to the O/D button on the end of the shifter get worn. Eventually the insulation wears off and grounds out on the metal in the steering column. Since i didn't think to take pictures when i did it, I'll be as descriptive as possible.
First you need to remove the radio and the main dash panel. This is the one that surrounds the instrument cluster and radio, and has the headlight switch, and (if equipped) 4 wheel drive switch, power point and passenger air bag switch on it. This just pops off, it will take a bit of effort but it will pull off.
Then you will need to remove the plastic around the steering column. The easiest way to do it is to remove the bottom half first, then the top half.
To remove the bottom half, there are 3 phillips head screws that you access from the bottom, they are recessed in quite far so you cant see them, but if you put your screwdriver in you will feel them. You will also need to remove the wheel tilt lever, it just unscrews. Then it should come off.
To get the top off, you need to remove the ignition tumbler. This is very easy. On the bottom of the tumbler you will see a little silver button, just turn the key to the "On" position and take your screwdriver and push that button, and the tumbler will come out. This can be taken out with the bottom half of the column still on, but its easier with it off so you can see what you are doing. After that the top will come off.
Now you should see the wires running into the shift lever. Taking the lever off makes this much easier. Taking it off is simple, at the pivot point of the lever you will see a small pin, just take a hammer and tap it out, and the shifter will come loose. Depending on the condition of the wire you should just be able to tape over the worn insulation, thats how mine was. If not you may have to replace the wire. Once you are done i would recommend putting extra electrical tape over the entire wire, plus a few extra layers at the main wear point.
Thats all, now you just need to put everything back together. No tricks to it, just reverse the removal steps.
