Unless its some fancy multi pin weatherproof connector that you have the proper crimped terminals and seals for I wouldn't recommend creating an additional failure point when a large flexible grommet is so easy and reliable.

Was thinking about getting a fancy deutsch connectors, I'm already going to be doing some anyway.
I've been debating about doing one of those in the crew cab. I feel like my grommets are running out of space. Every time I think I'm done adding circuits, I end up with another one. I was thinking it'd be cool to have a bulkhead plug with extra spaces. As Heath mentioned, the additional fail possibility is the reservation.
Check out Seals-it for different grommet options. I used a larger two piece seal behind my block so I could pass the ECU connector through the firewall to the ECU inside of the cab.
I did a Molex connector for my main harness when I did my cab swap. Pretty nice industrial style 1/4 turn connector with 36 total pins.
Working on the wiring now, ls harness is out and the cab wiring is just dangling.
Thinking if everything goes alright I could have it running again this weekend maybe.

More parts just ordered, 
For those of you that are fimilar with the holley terminator kit, could I use this bung in the headers for the o2?

Yes, that is fine to use that. Use a good gasket, any exhaust leaks will create a false lean condition the computer will try to correct.
Perfect, I figured it would be fine but wanted to double check. I know how critical it is on these.
I always thought the O2's were meant to be as close as practical, so they heated up fastest and stayed hot for stable readings...? Unless it was one of the stupid after-cat ones for emissions checking...
That is true for a traditional narrow band normal o2, this being a wide band it comes up to temp quicker but also requires more heat.
I think with the terminator x they don't require it as much, I remember this being something we talked about on the phone hints the reason why I asked. Here it is straight from the install manual.
If its in the collector I would be happy. I've done it after before, but prefer not to have after the collector because it's another potential exhaust leak to cause issues with the reading.
Every long tube I’ve run on different platforms has had the front o2 in the collector.
Were any of these using a windband o2?
I've ran widebands in the collector, most people with headers do. Run it and don't worry about it, just make sure there are no leaks.
Yup.
Awesome, thanks guys again.
The collector is actually the best spot, because it combines one whole bank, so you average 4 cylinders. If it was closer to the head it would only read one cylinder(or possibly 2 with the Tri-Y), and if it was further back you have an increased potential for collector leaks to cause issues.
