On the harness that came with my transmission, I found (2) plugs not connected, and a 3rd still plugged in. From what I can tell, the main plug may accommodate additional wires, but only has 3 being used. There is also a 2 wire plug that is I’m assuming should be plugged in, just haven’t located the location yet. My understanding is it came out of an 89 model Dodge van. Best I can tell, it looks to be the right transmission for the conversion.
