G20 Tranny swap

[paulbunyan]

All,
I have a 1986 G20 with a THM200/4.3l in it. The tranny bangs so hard that
the vans shakes a lil bit when I put it in reverse. So I pulled a THM350 from a 1985 G20 with a 350. Now, my question is, can I simply bolt
the TH350 into my 1986 G20? Physically everything looks like it will fit, but
the wiring connector does not match up. Can anyone tell me what I need to do
to get this to fit or does anyone know what type of car has a tranny that'll
bolt right up in there. I am going back to the junkyard this Sunday so I
probably can pickup another tranny then.
