I just finished swapping a 92 engine into my 90 pickup (3.0). It went well but I need help on the grey block that attaches to the truck wiring (kick panel on passenger side. Old has 12 wires and new has 14 (different size connecter), can anyone cross reference these ...Thanks. Pin layout for both years would do the trick.

I use the 92 ECM so OK there and one the white connecter plugs and plays. Just the grey one is troublesome. Wire colors and positions appear to be in differnt spots on the connectors. help.
