Bought an 94 si hatch for my 95 d15z1. guy that owned the si cut the wiring harness up. so I'm swapping in part of my d15z1 harness.

.. The guy cut the complete harness, right as they come into the engine bay (he cut the wires right before the connectors from the ecu to the engine harness)

.. so does anyone know if it will work to cut my d15 harness and wire it up to the d16 harness?

d16 wire count: 51
d15 wire count:52

anyone know what this extra wire might be? (counted both twice)

i think the extra wire is a big dark blue wire. anyone know what this is? or where i could wire it to the d16 harness?

thanks,
phill
