My car's going to out of commission for a little bit so I'm going to go through some more troubleshooting. Does anybody have a wiring scematic for a 97 b18b into a 1990 ef with a P75 ecu? I tried searching "obd2" and didn't get much of anything

I've got a obd0->obd1 conversion harness hooked up between the chassis wiring and the ecu right now. The dizzy wiring was matched and seems to be ok. Is there anything else?

any help is appreciated

if your going into obd 1 and want an ECU to match it get a 1992-1993 or 1994-1995 integra ecu which came in OBD 1 those years.
PR4 and P74 ecu are the code names

 

I already have the p75 in place and running the but I keep getting a code 43 so while the car is going to be down for a little while I am going to go through the wiring to ensure myself that it is not wrong.

btw, pr4 came on a LS and p74 came on a GS on after a year or two they both went to the p75

yea thats what I said, 92-93 integra had pr4, 94-95 had p74

 

ok well I have a P75 OBDI US 95 Integra LS/GS ECU thats already installed and functioning. I just keep getting a code 43. I want to double check the wiring while waiting on rear lower control arm bushings. Where can I find a schematic to check on the wiring for putting an obd2 ls motor into the car?
