Hey CentralCoaster - I bought one of American Auto wires. I got the big one 22 circuits. It uses weatherpack inserts and is two peice. It barely fit into the original hole in the fire wall and I ended up haveing to notch the bottom of the original whole to get it right. Here is a link to what it look's like out of the box and mocked up. I f you want picks of what it looked like now that I made some plates to fill in the hole and let it set flush let me know. Also American Autowire makes smaller bulkead connectors I think like 10 circuit and other sizes. Hope this helps -Jason
