308 GTSi smog experts, I have a question

Hi guys,

I have a 1982 GTSi (49 state verison) that I am trying to restore to Calif smog legal status.

All the smog machinery, plenum and throttle body were missing when I got the car, I have reinstalled everything missing. The throttle body I got did fit, but I don't know what year of 308 or mondial it came off, but it does fit the 3.0 plenum, I have 2 questions:


Questions:

1. The Mondial manual says the EGR electro-valve switch vacuum tube has to be attached to a vacuum fitting on the bottom of the throttle body, but on this throttle body I see no such fitting, so therefore should it be attached to the plenum, for full vacuum at idle, or some other location?


2. There is a pair of wires with female spade lugs coming out of the wiring harness just behind the throttle body, all other connections of the wiring harness are accounted for, except for these two Was there some kind switch on the throttle body originally?

Does anyone know what these two wires attach to? There seems to be nothing I can see to attach them to. Is there a microswitch on the throttle body sometimes ?

Thanks for the info.

Andy

 

the wires appear to be black.

 

yes I see where the fitting is, it's right on the edge of the throttle blade....I don't see that port on the TBI I have, mine is from a different model I guess. (it said Mondial on the part anyway) don't know what year mondial its off, but it fits..............

 

there are two lugs, one has 1 wire leading to the wire harness, the other has two wires leading to the same wire harness, can't tell the color, both look black, just dirty I guess.

I will clean off wires and see if colors show thru.

 

I see the wires in your picture but that's them, the wires I am referring to are underneath the dead center of the plenum, and the wire harness runs along the valley of the block just behind the throttle body,
