Ken,
I recognize the Molex name from Navy aviation, and I figured that there was likely some special tool for the connectors. The Painless instrument backplane harness has connectors attached, and the mating connectors are made up from the fuse block side in the car which makes soldering more of a challenge than on the bench.

Pat,
Your mention of solder flowing into the tube was one of my concerns, and I think that your up hill, minimum flux method will be the approach.

Thanks for the input, guys.

Roger, since it would appear that you will be terminating in very uncomfortable and tight quarters and if you decide to solder the connections I would tin the wires first. I once helped solder a radar connector in the nose section of a DC-9 and that was a challenge.
