I've searched for days and can't find a proper wiring diagram for my resistor, it's an OEM one... not sure from what year, but mine has 6 grey wires, and one white wire in the center....

The drawing shows the power wires on the left of the clips. (black with an orange stripe)

Can someone please explain exactly what I do here?

I saw that picture, I still have no comprehension of it at all... can someone please draw on my original graph for clarity of what exactly i do? I'm sure this will help others in my situation in the future as well.

You're going from this:


To this:


The 6 gray wires on your resistor box are all equivalent, it doesn't matter which injector you wire them to. The white wire needs to go to the +12V coming from the ignition switch.

So basicly, all of the power wires T off and tie into the same wire... That wire I cut and connect to the white wire on the resistor, then every other grey wire goes strait to the orange and black wire in each clip individualy... And I cut out those wires, not just T into it right?

Is that basicly what I'm trying to acomplish?

Ok so I think I have a good understanding here... But when I opened up my wiring harness.... It was completely differant from the picture.... And there was much more wires T'd in to eachother then I expected... Including a black and orange wire that T's into the number 2 injector I think and goes past the number 1 injector to god knows where... And I'm really scared to cut it out. I traced the wires all the way back to the firewall and still couldn't find where they all come into one wire.

I have never done it but I looked into it a while back and i think you
1) cut all the power wires off of the injectors (leave space on both sides so you can rewire).
2)take any one of the original 6 power wires you just cut and wire one of those up to the white wire on the box
3) connect the 6 grey wires to the wires you cut going to the injectors.

Thanks... Can anyone confirm this? That all I have to do is connect any of the black/orange power wires to the white wire?

As long as the gauge of the wire that terminates at the injector is sufficiently large, then you don't have to go that far back in the harness. I don't know if the size of the wire increases as you go up-stream, but I imagine it would. Basically you don't want to use too small of a wire.

the black/orange wire is 12V switched throughout the car. seeing as this is where the injectors originally get their power from, that would be the one to use, your just changing the resistance is all. I have heard if you trace each of the 6 wires back up the harness far enough they are all spliced together near the firewall. this would also be a good spot where you could steal the 12v (if that wire has a thicker gauge, if not don't even bother), but if you go that route then you're gonna have to cut your harness there and at the injectors which means you are cutting in 2 places instead of one.

as for wire gauge others can chime in but i thought they are all the same gauge. either way they are just injectors that require a small pulse really, and if you think about it they will be opening one at a time only with sequential injection (sorry 1jz guys). its not like coils where the power relates to how good a spark you get. either your injectors will open or they wont.
