anyone got any websites on:

pinouts from obd2b and obd2a so i can make a conversion harness.. (preferrable)

or wiring diagrams for both somewhere online..

some dude has a 99 si in his 98 ex, and of course the chassis harness plugs wont plug into the new ecu...

any info on obd2b->obd2a or the reverse would be greatly appreciated..

Just head on down to your local honda dealer and see if they will let you photo copy a couple pages out of the shop manual for both cars.

Both manuals list all the ecu pin-outs for each car.

I recently did this for a '99 accord with a '97 h22a in it.
I had to move all but 2 pins.

Not real fun.

wow. all but 2 pins.. sounds absolutely wonderful.. eheh.. yeah thats gonna be my last resort.. asking a shop if i can photocopy their manual pages.. but if i can find em online it'd be that much better.. hybrid has one up there.. but i dont think it specifies if it's obd2a or b.. thanks.. anyone else happen to have a location on it online?

Why not reuse a 96-98 EX engine harness and get a OBD2a to OBD1 harness adaptor and a OBD1 ecu? Everything would be a plug and play deal.
