harness (part number L480145305) to go from the stock CMP harness connector to the TRG-
002 CAM OUT connector. You will also need to install the correct connector on the harness
depending on the type of vehicle. See the instructions on pages 8 and 9 for more detailed
information.
• See the images on page 11 for examples of what the 58X and 24X trigger wheels look like and what
the 4X and 1X camshaft timing gears look like.
• To use the TRG-002 DO NOT change the front camshaft timing gear to a single tooth gear.
• The TRG-002 is designed to work with the 4X camshaft timing gear (images A or B on page 11)
and the 58X crank trigger wheel (right lower image also on page 11).
• If you are not sure what crankshaft reluctor wheel your engine has you can remove the crankshaft
position sensor and look through the sensor mounting hole to see the reluctor wheel teeth. For an
image of what the reluctor wheel teeth look like, look at the image found at the bottom of page 11.
• The “Crank In” and “Cam In” labels on the TRG-002 refer to sensor signal “In” from the sensors
on the engine and “Crank Out” and “Cam Out” labels refer to the
signal “Out” from the TRG-002 to the vehicle’s ECM or PCM.
• 58X engines use 5 volt sensor signals and 24X engines use 12
volt sensor signals for the camshaft and crankshaft sensors. The
TRG-002 supplies 5 volt sensor power for the 58X cam and crank
sensors and provides 12 volt sensor based signals to the ECM.
• This means the voltage measured on the “Crank In” and “Cam
In” wires should be 5 volt signals and the voltage measured
on the “Crank Out” and “Cam Out” wires should be 12 volt
signals.
• In addition to using the TRG-002 to adapt the camshaft and crankshaft sensor signals, you will also
probably need to change connectors, obtain adapter harnesses and/or change parts in order to use the
injectors, MAP sensor and/or MAF sensor on the newer engines (see the Optional Items list on page 1
for some examples). Contact LPE or your LPE distributor for more detailed parts recommendations.
• The factory Powertrain Control Module (PCM) or Engine Control Module (ECM) will need to be
reprogrammed in order to properly run the new engine due to the different engine characteristics
including: engine displacement, injector size, spark requirement changes, MAP and MAF sensor type,
RPM range, throttle size, etc. Reprogramming tools are available from LPE or many companies offer
custom programming services and chassis dynamometer tuning services.
• Some vehicles may need a higher flow fuel pump in order to provide the correct amount of fuel for
the new engine. Contact LPE or your LPE distributor for fuel pump recommendations.
• On camshaft phaser equipped engines (L92 etc.) you will need to switch to a non-camshaft phaser
camshaft, timing gear and timing cover.
• The TRG-002 has not been tested in late model 24X 8.1L truck engine applications.
• The TRG-002 is currently NOT designed to work on the front wheel drive GM V8 applications such
as the Chevrolet Impala SS, Chevrolet Monte Carlo SS & Pontiac Grand Prix GTP.
• Important information regarding spark plug wires and spark plugs:
• As with most in-vehicle electronics, LPE recommends the use noise suppression ignition wires
and resistor type spark plugs with this electronic control unit.
