CAUTION
NOTICE: All the plugs on the wiring harness are uniquely keyed and must be in the correct
orientation for the plug to install correctly in the receptacle.
8. Connect the two harness plugs, primary and secondary, identified as CIP-P and
compressor inlet pressure sensors installed in the induction system between the airframe
induction air filter and the turbocharger compressor inlet. Install the connector CIP-P to the
sensor for the turbocharger inlet on the left side (exhaust bypass valve side) of the engine.
9. After the engine and airframe engine harnesses are installed, examine the connectors on both
wire harnesses for damage. Look closely at the connector contacts (pins and sockets),
connector body, and back shell. If any part of a connector is damaged on the engine harness,
replace the harness per instructions in the latest revision of the TEO-540-A1A Engine
Maintenance Manual. If a connector is damaged on the engine airframe wiring harness,
replace the harness per instructions in the latest revision of the Aircraft Maintenance
Manual.
