With round body to left, connectors right, reading down the wires: E2 IDL VTA Vcc
They are varying resistance: 3 wire TPS is step.
I would write out the resistance between terminals and movement of sensor but I shall just suggest you go buy: "Max Ellery's Vehicle Repair Manual" Corolla's/Nova's 1985-1998 Sedan Seca Hatch"
It has AE86 stuff (some) covers bigport 4AG and some small port 4AG.
