Brian has been working on choosing all of the MX150L connectors for the car. Please document the work here.
Digikey and Molex part numbers for the following:

Connectors

This is documentation on my progress in choosing the MX150L Connections.
I first started figuring out the connections for all the LV (low voltage) connections then moved on to the HV ( high voltage) connections. Figuring out the connections between boards was easy to visualize with Aashmika’s wiring diagram.

I cross-referenced this diagram with the board schematic diagrams, which can be seen from our Hardware directory. Inside this directory includes various branches which include the boards that were assigned to specific team members. There is a table in the PROJECTS branch on Confluence which shows you what member is assigned to which board. Projects [MSXIV]
To better visualize the layout of the car, I referred to these layout views. These included where the enclosures would be located in the car.

From there, I made a table on excel displaying all the connections between boards, the number of pins going out of them, and the type of connector on each end of the connection.The table also showed the wire gage needed and whether or not the connection is high or low voltage.
After making sure that everything on the table was correct, going through it with Micah, I made a table for each enclosure, displaying the number of pins, wire gages, and LV/HV connections. The values on the tables point to the value on the previous graph, so changes on the graph will correspond to changes on this table.
...
Afterwards, I made a Parts section underneath each enclosure (can be seen in the figure above) which displays how many MX150L parts are needed for the enclosures. (Might need to change this)
A great resource that helped me figure out the types of connectors we need is the Molex brochure, which includes all the various MX150L tools and parts.

I again found the MX150L tools and parts on Digikey and made a table on the same excel sheet displaying their Digikey and Molex part numbers.

After some discussion, it was concluded that through-hole flanges will be used as opposed to no flange or rear mount flanges. Additionally, gold pins were prioritized but weren’t available for pins below 14 AWG. Cavities are used for filling in blank spaces in the plugs, but I don’t believe there are any. Additionally, I believe that we have all the tools that we need for crimping the wires so I didn’t include them in the excel file. (pls tell me if I am wrong about it)
Here are the Digikey Links for the materials.
