DX To ZC SOHC
Ok i just pulled my dx motor out of my 89 1.5L and im ready for the ZC single overhead cam to go in. I just was wondering how the wiring goes. I have the ZC harness on the motor already and it looks as those it plugs into the DX harness(by the black box) but there is one extra set of 6 wires? And the stock DPFI harness has wires coming from the upper right of the engine bay a single harness. I was wondering what plugs into them? Does the extra plug off the motor? If so how...i should have pictures up tom. Oh yah and does an 91 Si ECU plug right in?
P.S. If this sounds confusing, im new to honda sorry

Do a search for MPFI conversion. You have to use the old DX harness on the zc motor. And yes the ECU will plug right in.

Its much easier to use the DX harness, you'll only have to put 2 wires together instead of having to repin about 10 wires. MPFI isnt hard, adding between 4-7 wires depending on how you want to do it.
