This is the 700-cfm TBI Avenger assembly with 65 lb/hr injectors. Those two black plastic protuberances are the idle air control (IAC motor) on the upper righthand side and the throttle position sensor (TPS) on the lower right side. The barb fittings on the lower left side of the TBI are the 3/8-inch inlet (upper left) and 5/16-inch return (lower left). The IAC motor is flanked by a pair of vacuum ports with an additional port (full vacuum) visible at the lower right corner. The two pigtail connectors are for the air temperature sensor (blue and black wires on the left) and the main fuel injector harness (gray connector).
