Question:

How are you supposed to mount a 7-pin electrical box with this hitch? The safety chain holes stick out, with a box for a 7-pin connector mounted as close as possible, it doesnt clear the hole in the bumper.

I have a couple possible solutions, but I don't think the hitch manufacturers had a 7-way in mind when they designed the hitches. There also is not a lot of space to work with on the 2023 Model Y. As you said, the safety chain attachments are in the way on the # DT58MR, and the cross tube is in the way for the other option from EcoHitch # EH39FR.

I don't have the dimensions of the cutout, but it may still be possible to fit the 7-way to the left or right of the safety chain attachments. You will need to add a 4-way # 119250KIT and then a 7-way with the # ETBC7.

The width of the adapter is approximately 3" and you would need room to route the cables coming off of the back so you would need to measure the available space. Based on the pictures we have it will be close.

With the # DT58MR installed, it looks like you could also mount your 7-way parallel to the cross tube to the left or right of the receiver. Again, you would need to measure the space to see if it would fit but I believe it will. The 7-way doesn't have to run straight off the back of the vehicle.

I have attached some review and installation videos for your reference.
