Ground (BLACK) – This is used as the low reference (ground) for completion of the MAP, TPS, and oil pressure output circuits. It can also
be used for modules connected to either of the fused 12V outputs.
Terminals for the included mating connector can be acquired at a GM dealership in the Delphi Terminal Service kit (J38-125) in tray 8 position 9. At
most dealerships this can be found at the Service Desk.
NOTE: If you are using CP Supermatic Connect and Cruise kit #19257634 or 19257661 the Bulk Head Connector must be plugged into the CP
Supermatic Connect and Cruise harness. For the Connect and Cruise the tachometer signal and the throttle position signal are received through the
bulk head connector.
Service information Contact your Chevrolet Performance Dealer for Service or for instructions on how to obtain Service Manuals and Service

harness diagnosis (use this information for all LS crate engine systems).

How the PVC system works:
A closed crankcase ventilation system must be used in order to provide a more complete scavenging of crankcase vapors. Filtered air from the air
induction system (air cleaner) duct is supplied to the crankcase, mixed with blow-by vapors, and passes through a crankcase ventilation metering
device before entering the intake manifold. The primary component in the positive crankcase ventilation (PCV) system is the PCV flow metering
orifice. Vacuum changes within the intake manifold result in flow variations of the blow-by vapors. If abnormal operating conditions occur, the
design of the PCV system permits excessive amounts of blow-by vapors to back flow through the crankcase vent tube and into the engine induction
system (air cleaner) to be consumed during normal combustion. This engine ventilation system design minimizes oil consumption and significantly
reduces the potential for oil ingestion during vehicle limit handling maneuvers.
