@regazzoni,
How was the install? Did you do it yourself? I just ordered my SteathHitch today, to install over the Jul 4 long weekend, on my 2018 Model 3 LR. Planning on doing it myself. I had to go through some work-arounds to buy a 2020+ rear diffuser that has the hole already cut out. Tesla wouldn't sell it to me because it didn't come on my year.

Install was not that difficult. I put the car in the rear onto ramps.
However, I did run into some problem areas:
1.) removing the taillights was much more difficult than expected. There are two pins on the lights that gave me some issues. Could not find leverage with a trim tool.
2.) I was unable to unplug the bumper sensor plug. Tried everything, no luck. So, I ended up working on the car with bumper just lowered - which went ok.
3.) Installing the receiver block (two bolts) was difficult. There was just not enough clearance for wrench on rear bolt. I was hitting the trunk wall. I think it would be better to install that block before mounting the hitch frame.
4.) In retrospect I would take pictures of the bumper in advance. It is a Tesla after all. So, I questioned whether all the gaps/alignment fit of bumper are correct after reassembly. Didn't really remember fit prior.
Mine had the hitch opening already.
Took me about 4 hours.

Be interested to know how it goes for you and if yours has the harness (when in 2018?). What was the workaround method used?

Pretty sure everyone above is wrong.
That plug is for the optional Flux Compacitor.
A Flux Compacitor is about 10x the cost of FSD, so few get it

Old post but now find out that grey plug is for the official Tesla power trunk retrofit.
I have the power trunk retrofit kit but unfortunately I don't have this plug on my 2018 M3P.
Any idea what the part number is for that harness? Or could snag the harnesses up so I can connect Power to this power trunk.

Someone had an adapter for the bumper mounted trailer lighting Tesla connector for several hundred dollars on the internet auction website. I used a crimp kit to crimp on power and ground and routed them through a rubber grommet on the right side of the car to the inside for the smart trailer lights module. I used a crimp connector which had the same ID as the Tesla trailer hitch connecter pins.
