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.

 

Get pins at the junkyard, with a small enough screwdriver you can remove the pin and grab as much of a pigtail you need. If you get them anywhere else your going to have to strip it, crimp it, and your never going to get as good a crimp like a factory wire.

 

That sucks. The only junkyard around here is an hour and a half away. I don't have a car at the moment either. So I'll see what I can do.

These aren't sold new anywhere?

 

ANSWER:

Buy the harness pieces from someone or get them at a junkyard. $10.

 

I can sell you brand new ecu pins. A plug has its own pins. B and C have the same size.

 

I beg to differ. With the CORRECT tools you can get s factory crimp. You also risk damaging the pins when you remove them from old plugs if you don't know what your doing.
