I need to know if it is possible to use one of the adapters that i've found that adapts the OBD2 harness to the OBD1 ecu that came with my H22 for automatic transmissions. I'm pretty much stuck with the auto, and most of these sites that sell them say "manual-only". Is there another adapter out there for the auto-tranny? is it difficult to splice the crap out of the blue AT plug to make it line up with the OBD1 AT plug?
