I used the AstroFlight connector to regularly switch between a Novak 6.5 and 13.5 in my T4 and it worked fine. I recently went through a phase where I tried to reduce the amount of equipment I brought to the track so it was bye-bye hard wiring. I thought the connector was a little heavy though. The other thing is that this connector is not keyed, so you could put it in backwards if you are not careful. The way I have it wired, I'd really have to twist the connector to do that, but it's still possible. Here it is in the truck.
