Evening all.

Just putting an AE82 4AGE bigport into a KE70, something I USED to do all the time. Now I just dump dirty datsun motors in them. Anyway, I can't get the fuel pump to prime. Myself and a friend both agree that we thought that the "circuit open relay" had a negative output that you took the ground for your fuel pump relay to.

However I can't get a negative OR a positive signal from this pinout. WHY? Or WHICH ONE did I used to take it/meant to take it to?

My 4AG 86 has the same issue that I would like to rectify also.

Thanks, Matt.
