i already had mpfi so it wasnt that bad..you need to use your stock dx harness..but for the money i would see the guys at rywire..they made my swap alot easier and the chipped ecu i bought is i would send them my harness and let them do it, its alot of bullshit if you dont spend the extra money at rywire

pay the experts.

You use your stock DX engine harness, convert it to multipoint and add vtec wiring, obd1 distributor plugs, obd1 injector clips, block off plug instead of resistor box, and depending on what ECU you're using; 4-wire or 1-wire O2 sensor in the end of the header.

Or, this package on Rywire.com will get ya what you need:

Don't post misinformation. You can not use an Si harness.
