Hey guy's,

I'm looking for the pinout (wiring diagram ) for a 20b ecu, haven't had much luck so far. So any help would be appreciated.

Cheers.

i have an incorrect one, if you feel like wasting a week or two of time.

ive been involved with a bunch of these, you really need the dash harness from the cosmo. it does enough stuff that it doesnt run right, and making it is a no go due to the bad diagram.

bad diagram is from mazda too, c1989, possible they changed something later....
