I'm trying to find out what pin B12(black) runs through before it goes to ground. The schematic in the Renix Fuel Injection Manual I'm looking at is too fuzzy to tell.

I can't get it off the manual either. Do you know what circuit it is?

Just found this site. Good readable ecu schematic and pin I.D's.

Thanks. I like that link. I tried reading the same one you must have been looking at originally. Even tried a magnifying glass on the monitor. Too blurry.

B12 grounds at the dipstick tube stud along with B11. Injector and knock sensor grounds are on the same circuit but may have their own termination at the stud.
There's a splice not far from the ECU where B11 ties in with B12, wire to D1-3 and injector ground.

Tried a magnifying glass too. When nobody was watching.

Pretty stupid idea, huh?
I've got a good wiring diagram/manual right here on my desk. It's laid out differently than a normal diagram. Has sections like Ground Distribution, Power Distribution etc. If you need any help, let me know.
