Purchased a 1969 C10 Short Bed - Pleasanton, CA

Tonight I put the kids to sleep, grabbed a beer, and replaced the valve cover gasket on the 250. I also gave the valve cover a degreasing before I bolted it back up.

The rockers look sludgy, let’s see if this 250 will come back to life.

Also, I haven’t had a chance to trace these wires yet but wondering if you guys may know where each is going…

To clarify, there is a wire coming from the battery’s + lead into the pictured bank. Then there’s 3 additional wires coming off of that hot bank. Thanks

By the way, one thing I am not used to at all is how difficult it is to reach the back of the motor on these C10 trucks lol. For example, getting to those back valve cover bolts should qualify me for the next Olympic gymnastics trials

Attached is the wiring diagram for the truck. You’re talking about the junction block. I am not sure if the straight 6 has an additional wire. This will help you get started. If you trace them it will help you figure where they go.

The engine bays on these trucks are large, sometimes I use a small step ladder to reach the back.

Thank you for that!

It looks like one of the wires runs to the fuse box. The other is labeled “Engine Ham” … what is that?

And then I need to trace the 3rd mystery wire on my 6cyl
