is there a way to figure out which wire goes to which injector, i cut them to put resistors in and i dont know which one goes where.

hatchdrvr

why did you cut them if you weren't going to label them so you would know where they go?

Unless you cut them way back, they will be long enough to reach the proper injector. As far as polarity goes it doesn't matter. Next time lable stuff before you cut it so you don't look like and idiot asking how to fix your mess-up.

Of course you could always run a continuity test from the ecu plugs to the injector wires to determine which wires go to which injector

could you explain to me how you do that? I can't picture you trying to figure out which wire is for which injector.

Search there are some wiring diagrams of injector wiring since people did alot of dsm injector swaps. there is plenty of info on wiring.

oh yeah next time do one at the time or just get a damn resistor box it's cheap.

Are you for real???

Pull out your a connector to your ecu, and get a pinout diagram

you should have pins for injector #1, 2, 3 and 4..

Run a multimeter to test for continuity (audible is best), touch it to a pin, and then to one of the injector wires. When it shows a completed circuit, you have the right wire.

Oh yeah, since you thniking 2 wires per injector, they are paired up, so that should be easily sorted.

ABK

yeah but isn't a second wire ground? so you will always get the signal, so you won't be able to match up the injectors with wires?

I still don't get how that's supposed to work.

civic-4-ges

Second wire should be independant of the first, as far as signal. ECU pinout to injector signal wire should produce only 1 wire per each injector that will determine its desitination

ABK

okay this still doesn't make any sense.

Correct me if I'm wrong

okay one wire that goes to injector is ground (has nothing to do with detemining what injector it is) right?
second wire is positive (signal) from the ecu

okay you hook up a contiunity tester to it, it give you signal. Now how the hell do you know which signal wire goes to which injector?

civic-4-ges

By the Pin you are connecting to at your ecu. A1, A2, A3 A4 (depending on which ones it actually it). Each injector gets their signal from its respective location

ABK

yeah if you already know which pin/color wire it is why do you need a contiunity tester?

civic-4-ges

LOL...I guess I can't explain it any furtherthan I have, hence earlier when I said "are you serious".

Very simple concept/procedure. Hope you never have to doany engine harness work!

ABK

believe me I've done some engine harness work. Just what you are saying makes no sence. Since you already know which wire/pin goes to each injector there is no point to check if it got contiunity unless they are not opening up at all.
