NOTE: The Engine Preheat and Electric Element switches possess
Jumper Wires, which advance from Terminal 3 to Terminal 4.
Switch Panel Wiring:
1. Run 16-gauge wires from the switch panel to the elec-
tronic controller.
NOTE: It is recommended that the wire colors illustrated in
Appendix A be used when installing the switch panels.
This will ensure installation consistency, differentiate
between the separate switches and assist service person-
nel with troubleshooting.
Reference Appendix B for proper wire-gauge sizing.
2. Strip and crimp insulated female terminals onto each
wire at the switch panel location.
NOTE: Be sure to attach “Jumper Wires” where necessary.
Reference Figures 32 and 33.
3. Connect all switch wires to the appropriate switch con-
nections as illustrated in Figures 32 and 33. Reference
Appendix A for additional wiring information.
4. Insert all switch wires into the appropriate terminal/
switch panel connection on the electronic controller.
Reference Appendix A.
