Once you have the filter off, when you run the tractor, the filter's idiot light will be blinking on the dash. It's not hurting anything to run it this way, but the Data Logger can "tell" that the filter isn't there. Some guys have just left theirs on and let her blink. That's ok, but I disconnected mine at the data logger, and took it off. Mine sits on the battery hold down bracket, I'm not sure if yours is located in the same spot, but it likely is.
There is a retaining clip that holds the connector on the side of the plug:
Take a small, thin, flat screwdriver and insert it under the clip, and gently pry the tip of the screwdriver away from the connector to unsnap the retaining clip. In this 2nd pic, I have the blade tip just under the portion of the clip you need to pry outward on. Very little force here, you don't want to break the clip.
This next pic, the clip is loose, and I've pivoted the entire retaining clip to the right (in the pic) to be able to pull the connector off.
Here is the connector out of the plug. It was surprisingly tight to pull off, it was rather well sealed in there with that gasket. It pulls straight out and away from the connector plug on the logger.
I had originally thought to pull that entire portion of the harness off on my tractor. Once I started looking at doing that, I found it was much more intertwined with the rest of the engine bay harness than I cared to deal with. So I left mine in place, wrapped it in plastic and tied it up where hopefully nothing happens to it in the future.
I also took my logger off of the battery hold down bracket, and it's still sitting on the shelf in my shop next to my DPF filter.
