Installation:
• Make sure the ignition is off before beginning installation.
• You can mount the LNC-TC1 using the supplied hook and loop tape or the supplied self tapping
screws.
• Do NOT mount the LNC-TC1 directly on top of the engine or near the exhaust manifolds due to
heat concerns.
• Do NOT mount the LNC-TC1 in the line of site of high temperature objects such as exhaust
manifolds, turbine housings etc. If needed, put a heat shield in between the heat source and the
module to protect the plastic case.
• Do NOT install within 6” of nitrous solenoids or other devices with strong magnetic fields.
• If you have relocated coil packs, do not run the high
voltage spark plug wires alongside the low voltage
coil pack wires. Keep the wires as far apart as possible
and, if they do have to intersect, have them intersect at
right angles.
• Disconnect the pack connectors on each side of the
engine and then plug the LNC-TC1 wiring harnesses
in between on each side. It does not matter which
bank of cylinders each side of the LNC-TC1 harness
connects to.
Launch Control Installation:
• The wiring that is required is for the trigger wire(s) for both the launch control activation and
the load cell input. Depending on how you want to enable the launch control, 12V + or ground
activation may be used. Check some of the GM, LS1, Corvette, GTO and other forums for
discussions on other wiring methods. The possible launch control trigger/activation connection
methods are:
• Ground activation wire (green) - connect this wire to a source that supplies a ground path when
you want the LNC-TC1 to become active
• +12 volt activation wire (yellow) - connect this wire to a source that supplies +12 volts when
you want the LNC-TC1 to become active (i.e. brake light switch, line-lock solenoid)
• Switch connected in between the ground activation wire and the +12 volt activation wire (green
wire connected to yellow wire through a switch, usually a momentary switch)
• Ground activation wire connected to +12 volt activation wire (green connected to yellow) for
standard RPM limiter operation (LNC-TC1 always active)
• Set the desired RPM switch activation point using the two ten position rotary switches for the 1000
RPM increment (x1000) and the 100 RPM increment (x100). See Page 4 for example settings.
