Hey Vincent,
Below is a link that contains all the items I used to modify my mill. This was prepared for Chris Thompson (service manager at Tormach) so it contains more than you requested. I added the Fusion file for the magnetic junction box should you need to modify it.
I did another post with modifications to my 1500MX so there are images there of the other parts you may use. Here is the other post: Tormach 1500MX Firsts Impressions & Tweaks - Mill - Tormach Forums
I’m not sure what machine you are using, but if you drop the keyboard as I noted to allow space for the magnetic junction box, you also need to modify the handle brackets for the door of the mill. These are included as well.
Here are the aviation connectors that I used: Amazon.com: DIYhz GX16 4 Pins Panel Metal Mount Circular Metal Aviation Connector Adapter Male Female Plug Socket - 10 Pcs : Electronics
Let me know if I missed something, I will be traveling for the next few days.
Best… Richard
