i need to know which vacuum lines do what on the secondary controller on my '91

i also need to know which wire would be my signal wire for my O2 sensor(s) and which to tap into for the fuel/air mixture gauge

on the front head behind the Alt.... I think the rear sensor you need to tap into the blk/ppl wire.. but don't qoute me. You could just do a search..
As far as the vacuum lines.. what do you mean? There is a manifold to acctuator line, an acctuator to canister line, and a canister to secondaries line....
