I. Theory of Operation:
The Boondocker Control Box connects between the sled’s ECU (Electronic Control Unit) and the fuel injectors. It does 
not reprogram or communicate with the ECU. It only modifies the existing signals sent from the ECU to the fuel injectors. 
By modifying only these signals, it is possible to make fuel changes while keeping the stock fuel map. This means the 
ECU can still compensate for engine speed, throttle position, barometric pressure, engine temperature, air temperature, etc. 
 
The Control Box can reduce fuel or increase fuel amounts for certain rpm ranges and load conditions. This is done by 
changing its fuel adjustment settings by using the buttons and LCD display. As with tuning a carburetor, it is possible to 
go too rich or too lean! 
 
Note: Be sure you know how to properly tune an engine before you adjust the fuel settings! Use of an Air/Fuel Guage and 
plug readings are highly recommended when tuning. 
 
 
IMPORTANT NOTES – READ THIS!
 
Note 1: Never unplug the Control Box when the engine is still running! Electrical damage may result which is not 
covered under warranty!
Note 2: We recommend using Dielectric Grease on all connections to help prevent corrosion on the terminals.
Note 3: Avoid exposing the Control Box to environments where static charges may exist. For example, quickly
removing a sled cover from the sled in a dry environment can create a static spark that will damage the box (especially if 
the box is mounted up on the handlebars). 
Note 4: The Control Box is sealed – do not take it apart or it will no longer be sealed. The Control Box is designed to be
splash-proof. Do not submerge or subject the box to high-pressure spray. During long periods of non-use it is 
recommended that you do not leave the control box exposed to the elements. 
Note 5: Always use Resistor Spark Plugs! Non-resistor plugs WILL cause electrical interference with the Control Box. 
 
II. Control Box Harness Installation
There are two 10-pin connectors at the end of the black cable on the control box. One is for the EFI wiring harness and the 
other is for the optional Nitrous wiring harness. These two connectors are keyed (male/female) so only the correct harness 
will fit into the correct plug-in.
