Confirmation of FD Crank Sensors Polarity

Greetings y'all, i just came across 2 conflicting pieces of information and id like to clarify this with your help.

I need to confirm which is the right way of wiring up FD crank sensor wires. I have one set of info that tells me that the 2 sensor's wire color scheme is as follows:

Ne (+) is Black
Ne (-) is Red
G (+) is White
G (-) is Green

Then i have another set of info that tells me that:

Ne (+) is Red
Ne (-) is Black
G (+) is Green
G (-) is White

Also, i see that if you're looking into the sensors from the front, the + pin on both is the one thats supposed to be to the right, and the one on the left will be the (-).

Can anybody help me confirm this?

Maybe even possibly take a picture of a front cover so we can see the details? Ill see if i can do that from my end, but just in case.

Ok, i think i had the answer all along, i just checked my OEM documentation and it clearly states that the 2 (-) pins on both sensors eventually are common ground between them. And the colors are in fact Green and Red, so the Black and the White wire ARE in fact the positive leads for each sensor.

Now to clear up which is which, ill go look at a motor today and find out and report back.

Yeah, dont worry, i have the K2RD diagrams. FYI, apparently the K2RD site is permanently down. It was available up until recently, www.k2rd.com/haltech but i guess its gone.
