Blue Driver Wire (blue 12 awg) connects to the ground side of your stage 1 solenoids (fuel and
nitrous) or the first 2 solenoids of a 4 solenoid single stage
Red Driver Wire (red 12 awg) connects to the ground side of your stage 2 solenoids (fuel and
nitrous) or the second 2 solenoids of a 4 solenoid single stage
TACH Input (green) is designed to work with most Tachometer signals (down to 3 Volts), without the
need for a separate adapter. It can be connected to a tach signal, coil trigger signal, or fuel injector.
DO NOT connect it to a high voltage wire.
Throttle Input (white/red) is designed to work with most throttle-position-sensors (TPS) and wide-
open-throttle (WOT) switches. Connect it directly to the signal wire from your TPS. For use with a
WOT switch we recommend it be connected as shown in the diagram below:
Note: DO NOT connect other devices such as relays to the WOT switch.
T-Brake Input (red 18awg) can be used with either a 12-volt or ground signal to activate it. (see Input
#2 in the software section) Example: use this input as a secondary arm switch for applications that
use a trans-brake.
USB Connector should always be sealed with the dust cap when the extension cable is not
connected. If you want to leave the extension cable connected permanently, seal the connection to
prevent water and dirt from getting into the contacts.

The mini-controller will not turn on until the following steps are completed successfully:
1)
Disconnect the solenoids from the relays to prevent them from firing.
2)
Arm the MAXIMIZER-3.
3)
With the throttle in the idle position, press and hold the TPS learn button until the RED,
YELLOW and GREEN LEDs begin to flash. DO NOT change the throttle position until the
GREEN LED stops flashing and goes out. If the GREEN LED begins to flash quickly, you
have a bad TPS signal.
NOTE: The green LED on a new controller will flash when powered up. This indicates that the TPS is
not programmed.
4)
Once the GREEN LED is out, open the throttle all the way by pressing the gas pedal to the
floor and then release it. Repeat this step twice.
5)
Now verify that the GREEN LED goes off at IDLE and on at WOT.
