II. Control Box Harness Connectors
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 
transducer harness. These two connectors are keyed (male/female) so 
only the correct harness will fit into the correct plug-in. 
 
Note: Use Dielectric Grease on all plug connections to help prevent 
corrosion on the terminals. 
The Control Box EFI harness will need to be spliced 
into your sled’s harness as follows: 
1. Locate the fuel injector harness (see photo).
This harness comes from the smaller (26-pin) 
ECU connector. Cut away several inches of the 
black sleeve around the harness as shown. 
2. Determine where the control box will be
mounted and how the harness will be routed. 
Route the harness so the wires end up near the 
sled’s fuel injector harness. Be sure to route the 
harness away from hot areas and moving parts. 
 
3. If the sleeve over the EFI harness wires is too 
long, mark a cutting location, pull the sleeve off 
the wires, cut it to length, and reinstall it over 
the wires. 
 
 
 
Note on using the supplied Crimp/Heat-shrink connectors:
The supplied Crimp/Heat-Shrink Connectors, if installed 
correctly, will provide a reliable connection. After the wires 
are cut and the insulation is stripped, the connector is crimped 
onto the wires. The connector is then sealed by the heat-
shrinking process (adhesive inside the connector will melt and 
seal out moisture). Proper crimping and sealing is critical to 
the reliability of these connectors. When crimping, be sure to 
use the correct crimping tool. DO NOT USE A CRIMPER 
THAT PUNCHES INTO THE INSULATION. After crimping, 
pull on the wires to be sure they are securely crimped. Then 
apply heat to shrink the connector’s insulation tightly around 
the wires. See example in photo.
