Purple/green to the 2 post on the new plug which I think is ecm sender. Then the red and white to the 1 spot which I believe is the sensor return.

You are right.:wink2:

The return/sensor ground goes back to ECM, not a chassis ground. :wink2:

 

That’s how I have it all hooked up but it’s still turning the light on?

Are the two wire hooked up to a new WIF sensor that come with your new setup?

Its possible that the sensor is telling ECM that there is water in fuel.

The sensor is just a resister that the resistance will change when there is water in fuel.
You may be able to fool the ECM by playing with a variable resister in the position of the sensor.:wink2:

 

Yea everything is hooked up and spliced in. I have clean fuel it never set off the original one. Only thing I can guess is there must be something on the sensor or it’s not reading resistance right

I would try and find info on what newer severe duty sensor, from 4th gen??, uses ie voltage same ?? resistance value??

 

this. probl the new sensor operates about the same BUT has different resistance values .
isnt aftermarket stuff fun ?

 

Yes aftermarket stuff is fun. Even though it says OE I have modified this thing more and any filter base Iv ever used
