ok, I have a few questions, anyone who's done this, please shed some light.

We have all the obvious stuff. 4 Si injectors, Si intake manifold, and a wire harness. Now, my questions are these:

The wire harness is out of a 1987 CRX Si. The injector clips themselves are identical to the ones on my own 91 CRX Si, but the injector resistor boxes are not the same between the two year brackets. Can this 87 wire harness be used to make the Civic into a multi-point injection setup?

Do I need that complete harness? Do I need just parts of it? Where do I splice in the addition wires? Obviously we need the Si ECU as well, but I've heard that you also have to run a wire going from the ECU harness up to the engine harness. Please help. Any sites, pictures, advice, etc will be most helpful!
