I think the second connection is for the Lambda circuit frequency valve. Unless your fuel distributor has been tuned to run without the freq valve, if it's unplugged your engine will run real lean (ask me how I know). For in-depth knowledge, talk to Jim Fairman...he's a CIS guru.

Hard to tell what sort of mods your car has undergone, because apparently it doesn't need the freq valve plugged in and doesn't have an active Lambda circuit (oxygen sensor, et al).
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
