Whats the difference between obd2a and obd2b?

 

[scottp11]

OBD 2a: 96-98
OBD 2b: 99-

The OBD 2b ecu will not hook up to a 96-98 harness... I tried...

What motor going into what car?
I got away without needing a conversion harness
for an obd2 b16 going into my obd1 civic using the obd2a GSR Harness.

OBD2 GSr or type r in to a OBD1 Civic DX

I'm not more than 94% positive, but since the obd2 GSR harness breaks off at shock towers like the civic harness,it would be plug n play, except you will need an obd1 Ecu.

After re-reading your first post, i guess you weren't asking about the engine harness anyways.
If you go Type R, and want to use the Type R ecu, you will need to use an obd1 to obd2 conversion harness.
If you go GSR, just get an obd1 GSR ecu.

no OBD conversion harnesses required
