Ok, so I've got the engine wiring figured out (thanks axistr) and just doing some alterations before i drop it all back on the engine/gearbox. Of note, I decided to cut out the original injector circuits and run new ones along with an additional hall effect sensor wire to the distributor and this should future proof it for a different computer if i want. So instead of having the injector circuits spliced into two common circuits inside the loom, I'm running each injector circuit back to the computer and will common them up there. That way they can be separated in the future if i want to use a sequential injection computer.

For the electrical circuit geeks, couple of pics below.
