TPS prob?

I mentioned this problem in the Turbo thread as part of the ongoing saga of my son's 84 T1 problems, but this is probably a better place to get a response. The six way connector that comes from the tbody only has 5 blades on the male end. The connector looks pretty crappy in general, so I'm assuming one is broken off. The car has considerable lag at anything but WOT. I think that maybe it is not getting tps input and reacting only to the O2 info. Does this make sense? How does one replace the 6 way connector? Do you have to cut and solder? Thanks
