85 gsl-se how to disable smog pump?

I have an 85 GSL-SE (see b&brx8 albums) with 62,000 original miles. I would like to disable the smog pump, but I'm not sure what connectors/vacumm lines to plug, jump, disconnect bypass, etc. It is 100% stock, and unmodified in ANY way. Runs great, with a little stumble at idle sometimes that just recently surfaced. (vacuum leak?). I don't want to yank the factory cats (YES, it still has 'em), and have adjusted TPS, Variable resistor, BACV, etc. and tested ALL of the B.S. emission control systems, I MEAN ALL!

Replaced bad T.P.S. and O2 sensor just for shits and giggles. All plugs clean and gapped, wires ok. Coils and ignitors good (TACH WORKING FINE!) Done all this before, but had a 13b with a nikki 4bbl, so now my OHMMETER hurts. Any input would be helpful. Don't want to wind up with a hoopty that wont even idle or dies all the time. THANKS!

PS I alraedy have the dual alternator pulley, TYVM! Brian
