i have read the article here and on many other sites... but... the only thing i am confused about is the injector resistor box... i know how to wire up the injectors but, there is another wire coming from the resistor box, it is yellow/black and with the engine running it reads 12v in my Si. but in the article here, it says nothing about this wire. this is where the injectors get their power from so dont you think this is a key piece of information? hybrid garage says run it to the stock yellow/black wires on the dx injectors but they only read 9v with engine running.... can someone help please?
