Its a white two wire connector that leads to nowhere thanks to the previous owner, I believe ( everything emissions related was gutted w/ malice!) It comes off the passenger side main wiring harness that contains the WOT A/C shut off & and fuel something relays. Just wondering if anybody has an idea while I await the arrival of my 1992 EVTM manual. Also, has anyone had to deal w/ the cancer in this less-than accessible area?! So much for getting ready to start throwing parts at this thing!
