So I just swapped my motor/tranny from a 1995 into a 1993 body and am at the point where I am hooking the electrical back up and noticed that the part of the harness coming through the center of the firewall does not match up exactly with my 1993's interior harness. It seems the connector is the same, but I have a few more pins/wires included on my 1995.

Does anyone know what this part of the harness controls? There is also a smaller connector on my 1995 harness at the same part of the firewall that does not have a mate on the 1993 end at all...

I will have to get some pictures uploaded because I'm sure this is probably confusing as hell.

Help please!
