Default Re: ABS Pump/Module

I realize that may have been confusing. Honestly I was confused too as I was getting inconsistent test results
I really figured out end to end this time!
The PIN out for pins 3 and 4 of the ABS connector was reversed for the Wheel speed sensor. I switched positions of the pins and everything is working.
I guess when I connected the jumper wires I just randomly got the right wire to make things work, and didn't really think about the sensor wires being specific since it is basically an open close switch to my understanding.
I never thought the wires would be reversed as I matched wire colors when I soldered a new connector in and never touched the actual wire location in the connector, and it is impossible to tell which is position 3 and 4 from the manual.
Or maybe it is a change over years or aftermarket wheel sensors. Whatever the reason I have speed at all 4 wheels now!
