Thermoquad Problem

I think you got a later-model TQ with the extra smog junk on it. Hate to tell you this but I doubt it's going to work on your engine without a lot of tuning and modifications.

The idle enrichment solenoid richens the A/F mixture at idle so smog engines idle better when not fully warmed up. I'm guessing since your engine (what is it BTW?) had a Carter AVS on it there's no emissions junk on there, so you don't need the solenoid to work.
