System Features - Chevrolet Performance 19303139 Instrucciones De Instalación

The 3 ECM connectors are indexed to connect only in the correct locations. Install by pressing down firmly until the connector is
seated, then pull the top slider bar down until it snaps and locks into place. The bar should slide easily and will not move unless
the connector is seated properly, do not use excessive force.
Attach the harness ground eyelets (5 total) to the engine block using the 4 bolts provided, ensuring the connections are clean
and secure, and attach the fuel pump wires from the fuse/relay center FPPM to the power and groundside of the pump (this feed
is fused and relay-controlled from the ECM). Two ground eyelets should be attached under one bolt on the rear of the cylinder
head.
For manual transmission applications, a pair of wires for connection to a top of travel clutch switch have been provided. Not to
be confused with the bottom of travel clutch switch or neutral safety clutch switch which prevents starter engagement without
fully depressing the clutch. The top of travel clutch switch is used to briefly disable fuel when the clutch is depressed which helps
decelerate the engine and makes upshifting easier and quicker. A compatible clutch switch will have two pins which provide a
closed circuit when the clutch pedal is fully released and an open circuit as soon as the clutch pedal is partially depressed.
Make sure all intended engine and vehicle side connections have been made before proceeding to connect power.
Attach a 12 volt ignition switch feed from the vehicle to the pink ignition switch wire in the harness (this is required to enable
the proper power-up sequence of the ECM). This can be routed into the passenger compartment with the accelerator pedal
connector and diagnostic link connector. Next, connect battery power (minimum 8 gauge wire) to the horizontal stud on the fuse
relay center The other two studs are for accessories and are 50 amp fused), and the harness installation is complete.
Additional features and bulkhead connector descriptions are also included below:

System Features

• The Fuse/Relay center contains all required fuses and relays for proper engine operation. Spare fuse and relay openings are
provided for customer's possible future customer use.
• The Fuse/Relay center includes a malfunction indicator light (MIL) which will illuminate in the event of an engine fault code. See
your Chevrolet Performance dealer to have this code retrieved at the diagnostic link connector in the fuse/relay center (using
a Tech2 with Chevrolet Performance Diagnostics selection). Codes can also be retrieved using an aftermarket diagnostic scan
tool capable of reading this configuration.
Note that the MIL will illuminate when the vehicle is keyed-up - this is normal, and it will go out once the engine is started if
there are no current fault codes. A redundant MIL wire is included in the wiring harness to allow a light to mounted inside the
passenger compartment. The wire is located in the wire bundle near the pedal connector and the ignition voltage.
