Hi all, I changed the MAP sensor today, found a round two pin plug on the loom about three inches below the MAP plug , nothing connected, nothing obvious for it to join to. Two wires: yellow/ red and black/blue, what is it for? Thanks Ross

on my xg van that plug is connected to radiator reservoir which has a sensor but on my ute there is no sensor but the round plug is still in the wire harness hope that helps
cheers demmo
