you’ll need obd-I injector clips and a resistor box wired in to raise the impedance to the injectors. That is all. ---

[J-K-Tuning.com](http://J-K-Tuning.com) has the jumper harness…do you have the resister box for the injectors? i didnt have to change any clips on my car but i did have to trim down the o ring since the dsm injectors are a little bit bigger that honda injectors i just used a razor blade and some bloody fingers to get them to fit in right edit: wiring for resistor box [http://honda-tech.com/zerothread?id=517274](http://honda-tech.com/zerothread?id=517274)
