I swapped my 700r4 transmission and have these wires hanging. Does anyone know what they are to? 1983 gmc sierra classic.

It looks like it hooks onto a coolant temp wire or maybe a pressure switch for lockup. It's possible those wires haven't been used for a long time.

Thank you. I didn’t think they were necessary but wanted to make sure.
