Default h23a vtec JDM problems

i just got my JDM h23a dohc vtec fitted..the one with the blue head...it has an automatic transmission ecu and i am getting 2 codes....
17 and 36

the car will not rev past 5k and vtec is not engaging..the guy who is doing the wiring says the VSS code is malfunctioning so the car will not hit vtec.
it has an h22 93-94 model manual transmission which is OBD1 while the engine is an OBD2 99ish model..

he says it has to do with the VSS for the OBD2 engine is a 3 wire pulsing one.. and the VSS it has present on the h22 gearbox is OBD1 and is a 2 wire...
what can i do to get passed this?
i am in pakistan and stuff is not available here...i could convert over to OBD1 and chip or try to fix this problem so my questions are

1) does anyone have the pinouts for this rare engine which only came as an automatic?

2) where can i get the proper VSS for this setup and from what car etc. etc.

3) can i bypass the VSS in anyway? it is OBD2 so thats going to be very tough...

some help here?

This is true. What ECU are you using? If I were you I would be using a P28, but that's your decision...

Yeh but his secondaries wont be activated. If you car is already wired for obd2 you could run a newer prelude ecu.
