Default Quick Question

Replacing the EGR solenoid on my 85, and it looks like there is some sort of connection on the back side. This is the side towards the firewall. Mine has nothing connected there at the moment...should there be?? and what is it, if it is connected there. My vacuum routing doesn't show anything, so any help would be appreciated.



Cheers,
Michael

There is a vacuum line off the EGR's "hat" and the EGR Temp. Switch is located in the base of the EGR Valve.

From the EGR Temp. Switch there should be a (Grn I think) wire going to ECM pin D8.
