The stock LT4 intercooler pump is turned on and off by a relay. It has no direct control from the ECM. The LT4 ECM just tells the relay when to energize. The LT4 intercooler pump has three pins. Two of those pins are hooked up together and come from the relay. The third pin is ground. It wires the same as almost any intercooler pump.
