Certainly some sensors have the vent holes.  And some don't (those for
off road use that live down where they might get the occasional mud bath).
Splicing isn't a problem as far as I'm concerned with the conditions that
you give.

It's OK by me... I put a GM application sensor from NAPA on my
5kCSQ - cut off the GM connector and spliced it in (crimp connectors).
It was the cheapest option at the time.
