1JZ FC wireing help.

I have been told that wiring a 1JZ into a FC is fairly simple but no one has been able to tell me exactly what needs to be changed. Haven't found the info in any build threads and just need a little help. Plan on running stock 1JZ ecu supra or Soarer whatever one they send and car is a S4 N/A.

wiring novice with little but some experience. I understand the starter stuff but shouldnt we just run fuel pump wiring to the correct pins at ecu and run battery to correct pin? from the vid, we can just trace our oem coils presumably to the ignition fuse in the engine bay and wire jz coils to that and then same for fuel injectors, trace back to bay fuse. intercept the wiring going from fuse to ecu/ignition switch and tie that to the jz ecu correct pins. am i over complicating or mis understanding things?

my swap wont be happening for a year or more maybe. ill be sure to post all wiring pins and what goes where, wire colors for an 86 s4 anyway. if i dont just go stand alone.

theres actually a 1/2jz swap group on facebook with a lot of wiring diagrams with highlighted wires and function for many jz variants. just search 1jz swap. our cars only need 5 wires out of jz engine harness other then your coils/ignitor and injectors. well grounds too obviously. fairly simple, im not sure how the fc body harness goes though but getting it running is not too bad with the diagrams
