Hey everyone, I'm mid swap and about to venture into the wiring

I'll give you guys some info on the car
-Engine is from a jdm fd3s 1992 or 93. Here is the first question I've heard the engines are the same but the wiring is different between the years is there anyway I can tell or fine out which year the engine is?
-Has been swapped to single turbo, we've made a custom manifold and are running a holder h1c (twin scroll) waste gate is 50mm synapse, mazda trix vacuum delete for the twins
-Will be Running an apexi pfc
-EBC Instuments digi dash. Do not need to worry about running any of the dash stuff as it is completly stand alone

The car is an 1986 Toyota corolla gts usdm I have the diagram for this already

Basically need to know what I can delete from the Mazda harness and the question about the year of the motor. And if anyone had some info that would helpful id appreciate it much
