22-R to 22-RE

I have a 1994 hilux 22R carbi model and I am thinking of putting in a 22-RE motor. I have both manuals on the models as I think the 22-RE came out of a 4 runner. What sort of things will I need the 22-RE motor that I wont have alrteady in hilux 22-R???? I am only getting the motor, head, manifolds, longmotor and wirring to the ecu including the ecu and associated enigine wirring and relays.

After reading up on the 22-RE I see there is a lot of inputs into the ECU like 4wd detect, brake light, knock senser.....I need some info...any info that will be helpful for the conversion...I have another fuel pump arranged as I dont have the orignal tank. Any info would be great as well as any workshop manulas I might need....I am a electrian with electronics so I can read wiring schematics
