I'm going to replace the wiring harness on my 81 K-Jet soon and am planning for the job. I'm hoping a new harness will help smooth out the idle, as well as just being a good thing to do since I can see the old harness is deteriorating. I recently had the manifold off and replaced the injector seals, temp gauge sender, the heater hoses, the breather box, and all the vacuum lines under there. I also relocated the flame trap and cleaned up everything including the throttle body. Now that I have a new/used harness from from Dave Barton, I'm going in there again.

I'm thinking it would make sense to replace the following parts:

1. The rear under-manifold sensor/switch. I think it's the thermo-time switch that controls the cold-start injector.

2. The front sensor that sits under the manifold below #1. I think it's the ECT sensor.

3. Is Bosch the best brand for the two sensor/switches? Best source?

Questions:

Any thoughts or advice?

Anything I'm forgetting? I don't want to have to go in there three times. I want to catch everything on the second shot at it.
