Doing a b series swap into an EF (1989 HB) and my ECU is lacking pins. I totally forgot about this. Are all the ECU connections the same size? As in, A and B/C areas of the ECU being the same pins. And where can I get extra pins so I can connect my wires to the ECU?

I am not sure if these are the same size. And I don't know where to get pins. Can I get them at like Radio Shack or a computer store? Maybe auto zone has them?

ALSO! Important.

Some of the MPFI swaps and B series wiring says to connect, say for example, Vtec solenoid to A8. There is already a wire there. What do I do with that wire? Just leave it hanging? Connected to nothing?

Thanks a lot.

 

A plugs are different than B and C. Junkyard will have them. If a pin is in a location either depin or you can use that wire to hook up VTEC or whatever sensor.
