Now I don't know if this is normal behavior or I messed something up. I never noticed, in the past, if the EPS stayed on after I removed the fuse. I have been throwing the console switch at the appropriate times.
I would appreciate it if anyone could check and see if their EPS stays on after fuse removal.

Yes the EPS will remain active for some period of time (not sure what that is, but I don't think it's very long) after the fuse is pulled.

Thanks for response. I am very glad to hear that is normal behavior, was worried I might have messed something up.

On my previous 2015 Trailhawk, the steering would stay active for about 10 minutes or until the ignition switch was cycled. Note that powering the flat tow harness from the coach charge line does work, however, you must also continue to charge the Cherokeeís battery or it will get depleted during towing as it is what actually powers the steering. To do so you need to connect the charge line to both the battery and the flat tow harness and insert a diode between the battery and the charge line as described by Dan at the beginning of this thread. The diode allows the battery to be charged but prevents it from powering the flat tow harness thereby enabling automatic operation. I used this method for several years before trading the car and it was much more convenient that pulling and replacing the fuse.

Does anyone have instructions on the installation of the flat tow harness for the cherokee?

I have a PDF with pictures from FCA but it's too large to attach here. If you would like to send me a PM with your email address I can send it there.

I do have the charge line and diode already installed. I got curious and checked the current across the Jeep installed 10A Fuse holder with the EPS energized and measured about 0.4A. If this is the total draw of the EPS, it does not seem like very much.

It seems obvious to me that the total draw of the EPS is not across the 10 amp fuse on the flat tow harness as the steering will remain powered up for about 10 minutes after pulling that fuse.

There is a motor inside the steering rack. When the car is sitting, the motor is not drawing any current. Check the current draw while turning the steering wheel back and forth.

On a side note, the current goes "through" the fuse, and voltage is measured "across" the fuse

Regards,

Dan

Does the "10a fuse" line actually power the steering rack motor? ... or... does it activate a relay which connects/disconnects the circuit which powers the motor. If it's the latter, and if the relay has a time delay it would explain the delay in the steering rack motor which is seemingly active minutes after the 10a-fuse circuit disconnect.

Is there a thread reporting on whether the death wobble issue is solved on the 2019 Cherokees? How are they performing? Thanks

Excellent point.....There is a lot of stuff that stays energized for several minutes after you exit the vehicle.
