Updated 4-wire ignition module plug?

[Blessed66]

Hey everyone.

I was putting together my project and ran into a small issue. I have an original 1987 TBI harness (I've gone through it all, already) and purchased a new TBI distributor, and while I seem to remember everything matching up to the plugs, I can't get the 4-pin connector to plug in to the new distributor. Does anyone know if this pigtail/harness ever was updated? I did a little Google searching and didn't see anything, one way or the other, so I figured before I get too deep, I'd better ask.
