I was feeling bad for not having worked on the truck and therefore nothing to update the thread with. Until I remembered that the best part of having an old truck is driving it, which is just what I've been doing! Apparently this running driving truck thing is still new to me after almost 10 years of just having project trucks and "playing with the truck" ment spending time and money working on it.
So I've driven it to work a day here and there when the weather is nice. Few weeks ago drove it around on the weekend including going to an old farm auction. Today I drove it to work and some errands before and after hauling some heavy greasy stuff.
A few weeks ago I almost finished the research on my wiring diagram/harness.
The diagrams and discussion about them can be found here

Enjoying driving,
Grigg
