Replacing wiring harness

[blown motor]

Over the last three winters I have been restoring my interior. I'm hoping to finish that this winter. I will have the dash panels out to replace the panel dimmer switch, clock, tach and bezels. The dash pad and frame will stay in. Now I'm thinking of replacing the wiring harness also because there has been a few 'electrical renovations' done over the years by previous owners and myself. How hard is it to repace the wiring harness with the dash in?

If you buy the correct replacement from M&H wiring it's an easy plug and play replacement.

You may want to start checking now to see if one is available, as some of the harnesses are on back-order, and who knows for how long.

One of the things on the list is to restore the steering column. When I have it all apart should I replace the wiring in it or is it usually in good shape? I know some would replace it because it's apart anyway but if that section of wiring rarely, if ever, gives trouble because it's protected inside the column then I don't want to spend money on it.

I didn't replace mine, it looked and tested fine.  I tried to restore reuse whatever I could, to save $$$

Let me know if you want some help.

The only thing I don't trust about reusing the original harnesses is that it's still 40 year old copper....if it's ever gotten damp or exposed to moisture, you can be sure it's corroding on the inside

Valid point for sure. I guess we'll see what it looks like when we take it apart next winter.

I would replace the ignition switch and directional/hazard switch since you are reconditioning the steering column. It's easy to do, the parts are not expensive and they will plug right into you new dash harness. An ounce of prevention in here is cheap insurance. You don't want a no start issue. They seem to always happen at the worst time possible. Change your starter relay also, it isn't expensive either. All three are around $120 from Rock Auto if I recall.
