they got their head stuck in their asses.
all you do is take your harness and modify the hell out of it.
then you get and obd2-obd1 adapter harness for the ecu.
i just finished building a harness for a 97 civic dx to run an obd1 b18b in it. it is a pain, cause you have to change out about 10 plugs and relocate a few things, but it is not impossible at all.
