Guys I need a favor from one of you, i need a clear photo of the injector's wire plug while pluged on the injectors. I suspect that my injectors' plugs are opposite.

I don't know if that will effect the injectors or flow or not, I know DC current mind if terminals are mixed.

Specially guys with red 550 cc injectors. I would appreciate your response.

Big thanx in advanced.

Anyone please ?

Thanx a lot Jake. You are the man

thats what the boards are all about...



good luck!

Another question,

What will happen if I plugged the cable upside down? I can see that both cables are brown. Anyone knows?

I could be wrong, its been a while, but I thought there was a circular cutout on the top of the connector and a flat edge on the bottom..

Yes sir, there is no way you can messup. The stock clip will only go in one way.

Yep your right Jake, We just had one off a couple of hours ago !!

You can't plug them in wrong, it is physically impossible

Let assume that I could because I plugged it already and I can see that it is possible, and i can see that i holds very well unlike the stock way where the cutout is facing down instead of up. There is groove inside the plug that allow it to goes inside one part of the injector that is 45 deg to the x-axis of the injectors.

If I put it in opposite way, will it be a problem? Usually they label cables with different colors for different terminals (ground, positive, etc..) but in this case, both wires that go into the injector are brown.

I've never seen an injector that'll allow you to install the plug backwards so I can't really say if it'll work or not. If the plug can only go one way ( 99.9% of all injectors anyways ) than I'm guessing it's because it won't work backwards, if it would then they wouldn't make a groove as it's useless.

Injectors are basically solenoids. The injector harness will generally have 12V to one side and is ground switched by the ECU. Polarity does not matter. I have wired a number of injectors on cars. The only thing you need to be careful of is high impedance vs low impedance injectors really as far as wiring is concerned. What kind of issues are you actually facing?

ahmad0658

Thank you for your information. It means i can plug the wire in opposite way if i want to.

Well my issue, Injector 6 goes open circuit and then mis fire, The plug does not hold very well, and the click on the plug wire was damaged, I just replaced a while ago and it is ok now. I have not done WOT yet, I will wait until night where temperature is some how reasonable (34 deg C) at this time of the year and then make some road tests.

I plan to go to the dyno soon to continue my dyno tune but I would like to go and the car is in very good condition.

Update, I just replaced the plug "cut it and replaced it with another one" Also, did the same for Injector 4 because it went open circuit couple of times and since I replaced both plugs no issues.
