Bought a 1980 zx parts car today, in hopes of transplanting the FI system onto my 72. I got all the wiring off, but some of the wires attached to the distributor run off behind the fender. Im wondering if these wires go to the ecu. I was under the impression the distributor had nothing to do with the rest of the FI system. Is this true? What about on a 75 system? Im thinking about getting one of those too. Thanks,
