does anyone know if the wiring on an spi is the same as an mpi, as I have a 100 with a 160 in that appears to have an obd plug in and my spi doesn't. I'm swapping the engine and I'm hoping to just swap the engine harness and ecu. Hope I don't need to swap the dash harness too.

I think the wires in the engine bay wiring to body wiring plug is located in the same way at least so you should be able to swap the engine bay wiring loom over.

cheers bud was hoping that was the case
