coil wiring...this is a test

i have a 86-91 13b s5 single turbo motor from japan and i am trying to get it wired up. i have a diagram for the wiring and it shows that the coils are wired from a different harness than the engine harness....doesnt make sense.

does anyone know exactly which wires the tail and leading coil plug up to and where on the harness they are? i dont need my gauge to work and the moment since this is a dune buggy project. i will adapt one later.

Coil power.

I think the + goes to the ignition (switched) +12. The negative comes from the ignitors.

Now I will wait for someone to correct my stupidness.

lol im not getting it right either. i am really wondering about the pulse signal that comes from the ecu. the crank sensor tells is when to let the coil fire. just dont know which wire it is....anyone with a 13b engine would be able to see it. i just dont know of anyone that has one close by.
