injector wiring

[Volchok]

I was wondering if anyone could help me with wiring my new injectors. I have Titek 550's and just want to double check the wiring. From the stock injector wiring there are two wires

red - poitive
white/black - negative

is that correct?

on the injector itself both wires are gray one has writing on it. Which is which? I can't seem to find it anywhere on zilvia or the internet.

thank you

With aftermarket injectors it usually doesnt matter which wire goes to which as long as you make sure that you wire ALL the injectors up EXACTLY the same.

Exactly. Pick a side of the plug and use it the same across all four.
