have a cable looks like speedometer cable with a wire plugged to a round connector on cable,found it real hot when I had dash apart wiring up a toggle and relay on electric fan. does anyone know why it would be so hot,pulled wire connector and checked,looked ok,getting a good connection

not sure what your talking about try taking a picture of it that would help out

here are some pics

If it is your speedo cable, that is for a cruise control.
