Re: what is this?
I do believe that is for an emission thing that you probably don't need. No idea how it worked

Re: what is this?
smog equipment. ESC I think is what it was called. You can remove it, and the wires, and the little gizmo it controls in the vac mile going to the dist.

Re: what is this?
Transmission Spark Control -- TSC. The vacuum advance was disabled until the coolant temp is above 32 degrees, and the transmission is in high gear.
This system was on my 70 GMC. I thought that the TSC started in 69 but I have not been able to verify that.
