Step 4 - Connect LaunchMAX to 12v Key-ON Power and to Ground

• Connect Grey and Red Wires (grey cable) to 12v Key-ON Power.
Both of these wires must be connected to 12V when the key is ON and in the Start position. Solder connections if possible.

• Connect the Pink Wire (grey cable) to Vehicle Ground.
Choose a good ground and bond to gound with a solid connection (screw or bolt).
Solder connections if possible.

Step 5 - Connect LaunchMAX to One Side of a Momentary Switch and the other side to Ground

• Connect the Blue Wire (grey cable) to one side of a momentary switch.
Solder connections if possible.

• Connect the other side of a momentary switch to GROUND.
Choose a good ground and bond to gound with a solid connection (screw or bolt).
Solder connections if possible.

• The momentary switch should be Normally Open.
When the switch is pressed the two connections should make contact and activate LaunchMAX.

Step 6 - (Optional) Connect LaunchMAX to Momentary Switch & MSD 2-Step Activation

• Connect the Blue Wire (grey cable LaunchMAX) to the 3 wire connector on the MSD (Blue Wire)

• When the momentary switch is pressed (closed) ground will be applied to LaunchMAX and the MSD.

Step 7 - Use electrical tape to insul ate all connections, Reconnect EC U Plug , Reconnect Battery

• Insulate all connections using electrical tape.

• Reconnect the WireHarness plug to the ECU. Be sure to replace the tape that was removed in step 1.

• Reconnect the Battery

Step 8 - Test LaunchMAX

• Do NOT ENABLE LaunchMAX when the vehicle is moving. Catastrophic Transmission Damage may occur if the LaunchMAX is enabled when the vehicle is moving.

• Turn the KEY-ON and verify that the GREEN LED is ON.

• When the momentary switch is pressed (closed) the RED LED on LaunchMAX will turn ON. If the RED LED is on the TRANS-BRAKE is enabled.

LaunchMAX Install ation is complete.
