Hello Everyone!

So I acquired a very dusty 62 Bubble Top that has been sitting since the mid-80s. I'm trying to get it back out on the road this summer without doing a full restoration at this time and I'm struggling with parts interchangeability.

Specifically, I would like to replace the wiring harness front to back. The interior/gauges/electroni cs are all stock and I'd like to keep it mostly stock, except a new small block with HEI ignition, updated fuse box/radio, ect. I was looking at the American Autowire kits as they say they will plug right into the existing electronics.

Here is my problem, they sell kits for Impalas, Bel Airs (don't specify the Sport Coupe) and Biscayne. How many features do all these different models have in common and where does the Sport Coupe fall into the pack as far as suspension/body parts/electrical compatibility with the more prevalent models?

Any help is greatly appreciated!!

Original wiring harnesses are the easiest to use without much cost.
A HEI only affects the under dash harnesses and stock hanesses will work with HEI..

The aftermarket(not original) harnesses sold by American Autowire require splicing wires and also are very expensive -for what you stated that you want to do.

Impala and Belair are different harnesses normally only for the under dash courtesy lights and the dome lights and the taillights are different.

I have a number off original harnesses off different 1962 models to compare.

I sent you a private topic message.

I bought a 63 impala last year.Previous owners past changed it up to a super sport. The only thing that worked was the ignition would fire the engine.

I never been proficient at wiring. The only thing I could compare is the American Auto Wire Kit. Their instructions were so clear, you would have to try really hard to mess it up.

I rewired the entire impala in just a few weeks tinkering after work in the summer months.

I am sure they would tell you if that is the right kit for you. They were really helpful from the time or 2 I reached them for a technical question.

One thing to know, cheap electric crimps wont do a good job, so find some good wide and heavy ones. And don't skip solder.

Thanks Droopy and pvs409 for the info!

Pvs409 has some original harnesses available, so I'm going to crawl under the 62' and see how bad it is. If everything is brittle and shot, I'll probably install an Autowire harness and be done with it. I plan on having the car for a long time, so it will be a good investment.

Thanks Again
