Does the 700r4 Transmission use wiring for the lockup? It's an 84 k10

yes, there is a 4 pin connector on the drivers side of transmission just about the pan rail. Depending on which set up, there may not be 4 wires in the plug. There is a brake switch, vacuum switch that are also part of the system to lock the converter. Then there are switches inside the transmission on the valve body. 9times out of 10, when guys take the factory carb and emissions off, they just go ham on cutting wires and unplugging everything electrical under the hood, well, the converter switch is one of them. Also, there’s a coolant temp switch as well.
