ODB-II v2 and OBD-II v1 ECU Pinouts

I am picking up a home-made OBD-II v1 to v2 harness and would like to double check the wiring before in install it. (I am going to be using it to install a Comptech ECU for a 1997/1998 Type-R in a 2000 Type-R.)

Does anybody know where I could find the pinouts for v1 and v2 OBD-II ECUs? I have the 1997 Helms supplement, which should have the v1 pinouts, but am wondering where I could find the v2 pinouts.

I agree..the best way is to just get the 96-98 helms and a copy of the 99-01 helms to double check. Any other list you get doesn't necessarily mean its correct but it also doesn't mean you can't use it as reference. BTW..I think this might help a bit as well..

That one wire (mentioned on Brian99si's reply) is the single difference between Si's and ITR's
