the vacuum and wiring harness is essentially the same just in different locations, you may want to lengthen wires, shorten wires and or hoses. the flywheel the 16V is the one you need and you just bolt it up to the 8V in place of the auto flywheel and torque converter, its a easy swap. i wired a 16V motor into my 92 dodge daytona use a 2.5 8V wiring harness, so it know there really isnt any differences that will give you any problems. ive heard Alan say the wiring is the same before, vacuum harness is essentialluy the same also. shop manual for the motors can be of help
