I'm also looking for a bulkhead connector like this.
I'll need to pass 32 or so 18 gauge wires.
The milspec stuff is real difficult to understand. There is a huge variety...lol.
Each part is ordered separately. bulkhead receptacle, plug, inserts, seals, male and female pins, all separate.
This website has a lot of good stuff, including a 30 pin weatherpack complete kit, but they don't give dimensions, it looks kida big.

What solutions have others used?
I REALLY do not want to hardwire my EFI harness through a grommet.
