Molex pin header & mating alternatives

Hi All,
First time poster here and I appreciate any advice you can give me. Thank you in advance.

Plug information:
Pitch - 3.97mm
6 pin
Molex 397 KK series

I'm working on a project, a jumper / extension cable for an appliance Molex connector. My thoughts are something similar to this, but perhaps there is a better way.

I've been able to find the exact Molex connector that will plug straight in to the user's existing control board. So, success there!

I'm needing suggestions on the best way to allow the user to then plug their existing plug (exactly like the one shown above) in to my extension cable.

Obviously they make the PCB mounted pin header like this:
but, I won't have a PCB to mount this to - So, I'd prefer a plug receptacle (or create male pins out of a plug as shown in the first link)

2 things I'm stuck on are:
To save in assembly time - Ideally, I would be able to use a pre-crimped 6" cables that have one side with this connector:
but i'm not sure of what the corresponding male pin would need to be, or if they even make such a jumper cable (?)

Is there a male pin that I could plug straight in to the Molex plug that i've found?
The obvious draw back is that the plug would not be locked in place in any way. This isn't as much of a concern as the location of this plug would never be touched again once the connection is made and won't be subjected to much movement or vibration.

Sorry for the length, but wanted to be as specific as I could be.
Please let me know if you have any questions. Thanks so much!
