motor swap

i have a 1990 ford ranger xlt with a 6 inch drop all the way around, it is a 2.3 four cylinder 5speed, i have a 4.0 v6 and an automatic transmission....i am going to install it, what all do i need to do this....ha sanybody else done this...if so...let me kno some tips....thanks

Welcome to this forum! I've merged both of your threads together. Swap the drivetrain with the wiring harness, and the PCM. The 1990 uses EEC-IV. The 1998 uses OBD-II.

Welcome To The Forum! I've seen guys do this swap with an OBDI truck but not the OBDII, Which 4.0 does this have? The SOHC or OHV?

i think its the ohv, its from a 1997 ford explorer, ive got the whole explorer, i was planning on taking the wiring harness, automatic steering column, motor, tranny, radiator, and computer from the explorer, but i wasnt sure if there was anything else i might need like motor mounts or any kind of tips i need to kno
