Thread: 3.9L 14CUX, hotwire AFM, intake manifold, fuel rail and injectors onto a 3.5L flapper

I'm scratching for a project and I'm considering doing a bit of an upgrade to my 1989 RRC 3.5L by fitting the following.

All parts taken from a 3.9L

14CUX EFI computer
Hotwire AFM
Intake manifold
Fuel Rails
Injectors

My questions are.

is all this 3.9L gear just bolt on to my 3.5L?
are there any other parts I should be taking of the 3.9L?
am I missing any potential issues?

thank you.

AFAIR the only thing missing is a VSS signal. The vehicle speed sensor signal activates the injector cut off if the car is moving, revs over 1500,and tps under 0.49 volts.

it also increases revs when coming to a stop for a smooth 2-1 gear change.
