I had to quit for the day since I ran out of paint. That nut has a matching one just above it and that metal piece comes out. I think I will remove it tomorrow and investigate.
Any suggestions for things to fix while this is all open?
Err, I'm pretty sure lol. There isn't anything else the truck would have that required that kind of module (your truck is a manual shift so there isn't a control module for the trans anyway) Easy way to be sure is trace the harness out to it's source and you should find it's connected to the carb systems. Another thing you can retire from the truck to tidy it up, along with the spaghetti can of vacuum hoses.
What were they thinking when they made these things.. vacuum control circuits, solenoid shut-offs and a complicated carb set up - fun
