#265637 92 Integra's are OBD1. You can use the OBD1 PR4 thats present with your swap.

So to answer your questions:

use your stock engine harness, and modify it to fit. you may be able to use the integra engine harness, but I am not sure.

yes, it will swap over. you may also need the driver side engine braket (the one that bolts to the engine and the rubber mount) from a 94+ integra or B Series Del Sol

the engine is OBD1

PR4s only came OBD0 or OBD2

P74 and P75 are the OBD1 units to use.

PR4's did come OBD0, OBD1, and OBD2a Flavors.

P74 and P75s from are more commonly seen as they come from the 94-95 Teggy. I personally have a P74 ecu in my JDM B20 Delsol. However an OBD1 PR4 ECU could run it as well.

This is correct.

Since your swapping into a EG Hatch, you want to use Teggy moutns, Especally the Rear T Bracket, the Sol one only works in Delsol's.

According to the Honda-Tech ECU List. It came from a 96-99 Integra, Therefore it would be OBD2a.

My Mom's USDM 2001 Integra LS has an OBD2b P74 in it.

I have never seen a OBD2a PR4 in the US. They must be from a Foreign Country. Its possible they were in the US or Canada however I havn't seen one.

thanks for pointing that out, I am all open to finding out new information. (I didnt see a PR4 OBD1 on any of my lists)
How about backing it up next time. I know Chrono explained it, but back your own facts up.

#266083 Next question would be how would I know if the pr4 ecu is obd0 or obd1 cuz for sure the engine harness is different cuz one if the plugs won't match.

The numbers on the ecu are the following : 37820-pr4-l11
492-102060 ABL
