Wiring harness help 83 gmc k2500

[TJones]

Hey there, new to the site and looking for some help. I tried searching but didn’t really come up with any answers. I trying to get the wiring back together on new to me 1983 gmc k2500 originally a diesel but now sbc swapped. I ran into a few wires I have no idea where they go. Can anyone help me figure out where these hook up? First plug is dark blue, light blue and green. Second wire is a tan or faded yellow wire with black strip and blade terminal end on it. Third wire is a yellow wire coming from the lowest harness coming out on the driver side and last wire looks to be orange with an inline resister in it. All wires are coming out in the driver side. Any help would be appreciated

1st picture is your transmissions TCC wires. Mine connects to female connector directly above brake MC.

Being that it was a diesel. The other wires might be the ones marked by the blue arrow on the diagram
