Hello, I searched and and couldnt find anything on this topic. I have 440 GT-R injectors and a dropping resistor, and I was curious how you wire these in. Would it be easier to go buy 6 individual resistors from Radio Shack or to use the stock Nissan resistor?

From what I can figure out, I give the resisitor 12v switched power, then wire the 6 wires coming from it to the injectors, but how will they get pulse from the ignitor? Im stumped, someone please help.

umm the white/black wire on the injectors are the power side and they have the resistor inline. the other wires are the signal wires that go to the ecu. so put the resistors on the white/black wire on each injector and then the signal wires go to the ecu. i think the ecu grounds the injector on and off to make them fire.

I have 440cc injectors in my car and stock gtr register drop and it is pretty basic to do. Have a look at the GTR FSM and just go from that. Also, user 240+civic=pimp has one wired up in his car and can help you out. He's the one that told me what to do

Ohhhh, ok. I thought the POWER side was the side going to the ignitor! OK, so, wire the resistor to 12v switched power, and run the 6 wires from the resistor to the wht/blk wires on the 6 injectors. Seems easy enough, Ill check it out when I install them and do a write up on it, thanks guys.
