OK guys I am finally back!
I have looked everywhere, but this is not exactly the most common swap... Right now I am driving a 1991 Honda civic si hatchback. It has a B18b1 motor controlled by B18A ECU. The wiring harness has been butchered a bit... I have the full motor (distributor and intake wiring harness and ECU included) from a 98 HX
I also have a CRX HF transmission. Axles, and motor mounts. This is a fuel mileage build. Can that motor be ran on OBD1?

I don't know what all has been done to the wiring harness of my car so I really don't know if I can just to make a jumper to run the factory HX CPU... Is that possible? If so that would be the easiest. But I have no idea on this swap, being that my wiring harness has already been tampered with...

Also the b18b1 has a BRAND NEW transmission (cable) also has gready 4-2-1 headers, and skunk2 pro intake manifold, and new axles. they will be for sale after the swap.
