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.

Am I missing something? I just did mine, didn't have to remove the radio or anything other than the plastic around the steering colum. 3 phillips head screws.
Remove the neg cables off the battery/s. Turn ignition to run, press a button under the ignition switch with a 1/8 or so screw driver. This pops out the ignition shaft.

Top plastic cover comes off. undo the 3 pin lead out the shifter handle, pop out the shifter pin. Take it to your work bench and meter it out.

One of my overdrive wires broke after leaving the handle. A quick solder, seal, silicone, and replaced the assembly, good as new.

About 20 minutes for me. Now I use "Permetex "The Right stuff" where the wires come out from the shifter handle. Drys to a neoprene consistancy and provides a strain relief for those wires.

Also I found that the torq screws at the end of the shifter shaft were exceeding loose. This caused play in the shaft itself. In my case it took out the shifter shaft guide bushings. Might want to check that as well since you have it apart.

I guess taking the radio and main dash panel out isn't absolutely necessary, I just did because i had to anyway. I'm not sure if it would make anything easier or not.
