Something like this or this may be suitable.
We need a separate +12V for the peltier. PWM puts a lot of noise on the power line and grim has allowed for this (separate +ve). Reality...it should also be separate gnd as well.

The Altronics IP68 connector looks good. Yep of stuff I'm looking at and also in D sub. I looked for sealed USB....nothing available. USB was never intended for this. Probably why FADDY made a breakout for all this. Actually his last images, page 84 look, good. Hi Cam85m is obviously working well.
