This last section will be more of a discussion of alternative parts. You'll see why in a second. . .Cannon MS3102E16S-4S Connector
(Connector with the Grey 2-pin Insert)
So, why did I mention alternatives? Well, from my understanding, they used the MS3102E16S-4S connector on the new proton packs. The accurate connector piece, which is attached to the split loom/breathing hose assembly, is SUPER rare. So rare, in fact, supposedly production had to cast the ones they had to have them on all the packs. I've only seen 1 photo of one in private hands (sadly, I cannot share that photo).
With all of that being said, there are less accurate alternatives out there; specifically more modern connectors. So I will share some photos of those, as I have been hunting and purchasing parts for over the last year, or so.
If you plan on using this type of fitting, let me explain the part numbers for you. The example part number I will use is: MS3106A16S-4P
(this size connector will connect to the screen accurate socket)
"MS3106A" is the model type of connector
"16S" is the size of the connector
"4P" is the number and pattern of the electronic connector inside the fitting. "S" stands for socket and "P" stands for plug.
So if you you have part number MS3102E16S-4S
as the socket, you will need MS3106A16S-4P
to fit that plug. For most people, the most important part of your search will be the "16S-4P" part of the part number, as that will let you know if your parts will fit together.
With all of that said, let me show you some examples of alternatives I have found so far. This parts work, but do not look exactly the same as the screen used part.
Here is one version of the connector that fits with my socket with the plug insert with 7 pins.
They can be torn apart as well. The parts are all interchangeable, as long as they are the same size connector.
If I ever get more information about the accurate plug, I will post it here.
With that, happy hunting!
