Identify Transaxle wiring connections

[fixkick]

One of my projects is to get this rebuilt engine to run outside of the car - I plan on putting this engine in my 4x4 buggy. It's a 1.6L 16v from Suzuki Esteem (automatic transaxle), coil-on-plug, distributor-less. Same as the Suzuki Baleno outside North America.

I'm am currently trying to get the harness sorted out and set correctly before I plumb the gas. The current issue is:

- What are these connections? Do I need them to start/run the engine?
#1 - shifter position?
#2 - ?
#3 - ?
#4 - ?





This is how I plan to get the engine started/running. It's mounted on a stand with radiator, steering and gauge cluster. I have not cut anything significant from the harness, so it's is about 98% of the entire wiring from the car.

Suzuki Esteem what year is it.?
the manuals for it are year based.
and all that is covered in the manuals real an online,   I presume you have the esteem ECU and harnesses
the shifter position would prevent cranking the engine not in park or neutral.
its an  automatic and has  speed sensors to shift correctly via the TCM (TCM may be inside ECU, forming  a PCM)
what matters first on all cars is year,  all books based on that.
