The ESC 1st gear switch on a 1984 manual transmission truck has a two-terminal Weatherpak with Green and Yellow wires. Yellow goes back to the ignition Crank wire just before the Clutch interlock and Green goes to the ESC computer.

Good call had time test start taking it out. And it turn out that it is set up for Dual trans wiring for A/T and M/T backup light. 700R4 wiring, Dual Dist. wiring. I'm really happy I grabbed this wiring harness did the 84 change over.
