Hi to anyone reading this, hoping some one can point me in the right direction.

Have a 4age blacktop going in my AE71 panel van, up to wiring in ecu.

All's going well up to CAS wiring, I searched and found out the pin outs for DIZZY/CAS....

On the Toyota OEM CAS side of wiring I have;-
Black wire = NE / Engine RPM
Red wire = G1 / Crank shaft position signal
White wire = G / G1-G2 common earth
Green wire = G2 / Crank shaft position signal [read that earlier model MTX8 not used by microtech]
*if incorrect can someone point out

On the Microtech 4 pin Crank input wiring I have;-
Black wire = GRND [which I take it is G]
Red wire = Not Connected [Used for Fuel only config]
White wire = Crank input 1 [is this engine RPM or Crankshaft position signal?]
Green wire = Crank input 2 [is this Crankshaft position signal or engine RPM ?]

After scouring the internet for many many hours/days, I cannot work out if crank 1 is NE or G1
same for Crank input 2...

I can't access the CAS to pull down and physically look, as no room, firewall too close....

Any help would be much appreciated.
Thank you for reading.
