Additional Notes
Important Information regarding spark plug wires and spark plugs:
You must use noise suppression ignition wires and resistor type spark plugs with this Controller. The
LNC-002 Controller contains High Frequency Digital Electronics and will NOT function correctly
without Noise Suppression Wires!
Nitrous, line-lock, trans-brake and other solenoid usage warning:
LPE has found that these solenoids can cause fly-back voltage levels at times in excess of 600 volts.
These voltage levels have the potential to damage sensitive electronics including the LNC-002, the
PCM/ECM and other modules in the vehicle. Lingenfelter Performance Engineering has developed
a transient voltage suppression (TVS) diode kit (PN L450080000) for use with line-lock solenoids,
trans-brake solenoids and other aftermarket automotive solenoids of this type. LPE recommends the use
of our noise suppression diode on all vehicles that have a line lock or trans-brake. This kit comes with
one TVS diode. If you have a vehicle with multiple solenoids we recommend obtaining additional TVS
diodes for those solenoids.
Troubleshooting:
• Intermittent misfire or other erratic vehicle operation.
• Disconnect the LNC and see if the problem still exists to confirm the problem is related to the
LNC. If the problems goes away when you disconnect the LNC from the system, re-install the
LNC and re-route the LNC wiring harness away from the spark plug wires and/or ignition coils.
Also try mounting the LNC in a different location. If you are using aftermarket spark plug wires,
try changing back to the stock spark plug wires or a different brand of spark plug wires. Make
sure you are using noise suppression spark plug wires and resistor type spark plugs.

Example wiring diagrams:
The following pages show examples of how the LNC-002 can be wired in different vehicle applications.
Many other possible installation methods exist.
• On manual transmission vehicle applications please note that most GM vehicles have two clutch
switches (a cruise control switch at the top of the travel and a neutral safety clutch switch at the
bottom of the travel). Make sure you are connecting to the correct one. In testing LPE has found that
the upper clutch switch (cruise control switch) has arratic output and causes improper operation of
the LNC. The wiring diagrams on the following pages show how to connect to the correct clutch
switch. On 2008-2010 Corvettes and 2010 Camaro SS GM has switched to a signal clutch position
sensor with a 0-5 volt output. The output of this sensor is actually from high to low. The clutch
position sensor will not trigger the LNC directly or most relays and a TPS/clutch switch most be
wired in on the vehicles. This switch is available from LPE as part number NO-00-6102.
