Connecting wires on 2 sides

[toiletmirror]

Hi, a little backstory.

I'm a university student doing a project that requires me to have a server inside a sealed chamber (vacuum).

The thing is the server's power-on button is connected to this little board here: https://imgur.com/z5oeJnS (beside my thumb) and this is the back: https://imgur.com/AfT74nC

It has 13 wires connected to each spot. Anyway, what I'm planning to do is to weld a KJL 15-pin d sub flange: https://imgur.com/OpJO1Vp (front) and https://imgur.com/HWw06rr (back) onto the wall of my chamber.

Then I would cut the 13 wires somewhere in the middle the length, soldering each wire to 13 of the 15 pins in a 1-to-1 positioning, with the little board/button on the external such that I can power on my server from the outside.

So before I jump into this, I'd like to ask for opinion, whether this is a good idea or not. I'm just hoping the 15 pins just work as a conductor from one side to another, and I'm not missing out on anything that may cause any short or open circuit. I'm just a mechanical engineer, and a student at that, so my experience with electronics is rather lackluster.

Thank you.

Hello toiletmirror,
If I'm reading correctly:
You're going to install the sub-board you are holding into a vacuum chamber, and interface it
with DB15 connector?
If so, then there's nothing wrong with the idea.
You just have to ensure you ground the connector to the chamber with the original connector
ground.
It wouldn't hurt to use heat-shrink sleeving on each wire end to insure better insulation between
each pin.
Its also important that you pre-tin the ends of your wires prior to attaching them to each pin.

Hmmm, I attached a drawing of what the setup is: https://imgur.com/LtbLbCC
Not exactly an artist here, sorry.

Insulation and coating should be fine here. Just curious about your mentioning of grounding... Sorry but what do you mean by 'grounding the connector with original connector ground'?

Thanks for the reply, though!
