Electrical wiring diagram/pinout TIPM?

Hello,

I would like to get the wiring diagram and pinouts for the "B" connector in the fuse box/TIPM.

My vehicle will randomly "stall" mid drive.
I can tap on the fuse box, and it will usually start right back like nothing happened.
Otherwise, it will just sit and attempt to crank without success- until I wiggle some wires.

I've narrowed it down to a bad or loose connection in connector "B".
While the car is running, I can wiggle this connector and it will shut off.
I want to test each wire with a multi meter and see if I can find the wire(s) responsible.
I do not think the issue is in the IPM itself, but that will be my next course of action if so.

I am hoping to repair/replace the plug without having to run major wires out of the IPM itself.
I am familiar with a multi-meter, but I don't want to accidentally short another module that may be connected. A pinout will show me how I should be checking each wire.
Researching, I've seen this random stall issue on these models in a few cases without any luck finding a fix. This information will certainly be helpful to anyone who wants to search in the future.
Thank you in advance for any assistance you can provide!

Included a photo for reference. Picture is from another IPM and plug from a salvage yard. Mine are still attached under the hood but they are the same.
