A yellow connector. Two sockets. Maybe a black rubber boot around it. Located b/t the afm and the boost/pressure sensor. It is not connected to anything. It's called a Fuel Pump Check Connector. When you jumper it, it puts a ground on the Circuit Opening Relay and IF the key is to ON or better, the fuel pump will run pressurizing the fuel rail to approx 37psi if the engine is not running or approx 28psi if the engine is idling.
