My '65 C10 started doing a wonky thing, sometimes the starter would not do anything... and I replaced it earlier this year.

Then it was doing the same thing... of course when I was out and about and on the other side of the big city I live near.

I started some basic troubleshooting and found the small wire going to the starter was cracked in places. I wiggled it, it started right up.

I wound up replacing a good part of that wire and thought it was all good... but, nope.

After a doctor appointment one day, same thing... it hit a lick, then it wouldn't.

HMMN.

wiggled the wire, and it started up.

I started checking it out... the wires going to the main engine harness plug wire on the passenger side of the firewall looked like they were ready to give up the ghost, right where it went into the plug. Hmmn.

Many years ago I had to replace one of those wires... so I unsnapped it and two more wires broke off.

I broke out the soldering gun and what not but I was having no luck this time getting going in the direction I wanted, so I just ordered a new engine harness.

Then things got interesting, seems there were different harnesses, for a 6 cylinder with gauges or lights and for a v8 with gauges or lights. Now, I have gauges, so that part was easy, but I have no idea what engine it had originally. Hmmn.

I went with the v8 with gauges, figured I could make it work.

The box arrives, I check out the goodies... yay new parts.

I start looking at the instructions layout... it was pretty neat, they had each wire numbered with a sheet of paper listing what each one was for. However, it was for the very original layout so I had to do a little internet searching to figure out what I needed.

After that, I basically only needed to hook up two wires, 1 to the HEI hot ignition and the other to the small wire going to the starter. I taped off the other wires as my gauges are wired in other ways(previous owner) or not working at all... though I think I will investigate hooking 'em up later.

At any rate it all fired up and runs again, so yay.

Old Trucks are fun.
