Which Injector Wire's are Postive?

[NewTurboTuner]

Im installing 2150's in my car and have to cut off the old injector plug so I can wire-in the new plugs ...can't find any info on which side &/or colors are the positive sides.

Any help would be appreciated!

Thx!

On the injectors themselves, its labeled which lead is the positive one, just follow the corresponding wire back to where you can see the color.

Referring to the stock injectors

Thanks ...I heard that before but I don't have any injectors for reference.
I already sold the injectors im replacing.

I know which side is positive on the new injectors, and I know which side is positive on the new injector plugs .....But Im unsure which side is positive on the original injector plugs that are on the harness. I have to cut them off, and match the positive side to my new Plugs.


I initially thought it didn't matter ...but now im 2nd guessing myself.
Can anyone confirm that it doesn't matter which side I connect them too?

Thanks!

Well here are some black tops

That's how they sit on the rail too, so positive would be on the right looking at the car from the front.

OK good enough I guess.
Thanks man!
...I appreciate it!

It does not matter if you cross wires when splicing in the pigtals for the 2150's. Anyway you install them will be correct.

If you're standing at the front of the car (at the bumper) and looking at the injectors, wouldn't the positive terminal be on the left? The positive is on the transmission side since the connectors point upwards.

Unless we're getting our "from the front"s confused

It's irrelevant.

It is irrelevant, but really it would be fairly easy for anyone who knows their way around a test lamp to figure this out. I would look for a new automotive technician.

I should have a voltmeter or atleast a test light, but I don't . Shame

This is true

An alternative way is to use the good 'ol look-it-up method

As stated it doesn't matter, because injectors are essentially solenoids. But, if you want to be OCD about it, have consistent wiring, and care that this post is not in vein, continue reading.

GO-GO GADGET SPOON FEED!
We have two relavent tech articles, in this case:

We can now determine which wires go to the ecu and which ones go to the resistor box. I'll do the first one for you...

Injector 1
Looking at injector one, we notice it has a red with blue stripe (RSb) and a green (G) wire going to it.
Now, using the ecu pinout we look up injector 1. What do you know? It's green! So, the RSb wire goes to the resistor pack and the G wire goes to the ECU.

I'll have gofer explain the ground: FIC 2150 Owners Please Read - how to wire in #2

There ya go!
