1960 - 1966 Chevy C10 Wiring Harness Cleanup - '60-66 C10 Custom Rewire

The throttle knob screws onto the throttle cable shaft. Notice the flat on the shaft, the flat was held still with an open-end wrench then the throttle knob was twisted counter-clockwise to remove.

Trying to work around the steering wheel is dumb. Some steering wheels can be removed without a puller if they have been removed several times in the past. After a good Maxifilm soaking and the steering shaft nut removed I applied firm upward pressure and then rapped it with a brass hammer.

The steering wheel popped off, and then it was time to remove the turn-signal mechanism by extracting the three Phillips head screws retaining it.

Replace as necessary: It's always a good idea to inspect parts considered for reuse closely for damage. Notice the irregularities in the wires, this is caused by heavy electrical loads heating the wires, and they are subject to shorting out.

The turn-signal mechanism is removed complete with harness by unscrewing the two 5/16-inch hex-headed bolts found on the underside of the steering column cover and sliding upward as shown.

The gauge cluster is held in with four Phillips screws. Removing these four screws only gives one false hope the cluster will be easily removed.

Before discovering what a bear it is, the mechanical oil-pressure line must be removed. It was easiest to remove it from the engine (next to distributor on the drivers side).

Notice the instrument face's black edge extending beyond the outer edge of the cluster. Because this sticks up, it catches on the dashboard. Notice where it is bent, this is a spot where it got hung up.

Look to the bottom left of the cluster opening and you will see bent metal near the throttle cable opening. This is another spot that caught while removing the cluster and got hung up. It takes a lot of jiggling to remove the dash cluster.

Tag it and bag it, or at the very least it's a real good idea to contain the parts as they are removed.

Planning ahead will save time. As part of the '66's new Keep It Clean Wiring installation this stock alternator with an external voltage regulator will be replaced and all of the related wiring eliminated.

This one-wire internally regulated Delco alternator requires less wiring, and everything needed to do the job is included with the Keep It Clean Wiring harness. Further considerations should be made for mounting new horns, etc.
