I've looked everywhere, I'll try to add a picture of one end. It's a wire connector, one end is 3/4 round 1/4 flat and has a two wire female connection. It branches off the harness on the passenger side of the intake, right where the temperature sending unit is. One plugs to the sending unit, and the other is right there like it forks off. I believe it is part of the evap emissions tube, the wire that plugs into the purge solenoid. It plugs into the plug near the sending unit, then plugs into the purge solenoid, one end 3/4 round and the other is square. I know this seems a little stretched out to explain, but it has something to do with the vapor tube going from the tank, to the vapor carbon cannister. Does anyone know where I can find that wire harness? Mike D. ( ITLRUN ).
