1994 4.0 vacuum diagram. I bought a 1994 B4000 LE 4X4 Extended cab that had 2 blown head gaskets for $300. Picked up a running 1996 Explorer with a bad transmission. Started engine SWAP, then had a fall, requiring shoulder surgery. Now 3 months later, getting back to finishing swap and have no idea where to find a vacuum diagram to finish! Can anyone be of assistance?
