The factory wire from that foamed connector powers the Map , The Alky was tied in with it an the 3 wire connector on the other side had loose pins. The Loose pins Alky power source would short out taking the Map Sensor with-it back though the foamed connector...When the connector cooled just from 5v ran through it ,it connected again...lol..what a PITA..It's all re-wired/re-connected/re-pinned now,The Alky's getting 5v from separate isolate source on the foamed connector now...Runs smooth as Silk....(we had to kill the rat by yanking the nest out,it's helped us find the problem)
