Design Intent:
• These wiring harness kits are designed to enable a simple and dependable installation for high performance electric
fan(s).
• They are compatible with all vehicles and can be used on any positive or negative ground 12 volt DC vehicle with no
modications.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vices where they will be as dry as possible and the least exposed to extreme temperatures.
Installation of the Temperature Sending Unit:
•DO NOT attempt installation when the engine is hot.
• The temperature sending unit is designed to mount in the intake manifold for the most accurate control of the system.
• The switch has 3/8”-18 N.P.T threads and will work in many applications. A 1/2” N.P.T. adapter is included in the kit if larger
threads are needed for this switch installation.
•DO NOT use “Teon” style tape on the temperature sending unit as this could cause a poor electrical ground and improper
operation.
• If you need to cut and splice the wires, use the provided butt connectors and shrink tubing for a proper connection.
See page 5 for installation instructions and pages 6 & 7 for wiring diagrams for
vehicles without air conditioning and pages 8 & 9 for vehicles with air conditioning.

Design Intent:
• These optional high amp toggle switch harness kits are designed to enable simple installation of high performance elec-
tric fan(s).
• It is a universal t. It can be used on any positive or negative ground 12 volt DC vehicle.
• These switches can be used with or without a temperature sending unit using the diagram on pages 17 & 18.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vice where it will be as dry as possible and the least exposed to extreme temperatures.
Theory of Operation:
• When the temperature sending unit reaches its operating temperature it brings the attached wire to ground.
• When this happens the relay is “turned on” which, in turn, operates the electric fan(s).
• These manual high amp toggle switches serve as a bypass to the temperature sending unit and will operate the fans at
your desired temperature.
Installation of the High Amp Toggle Switches:
•DO NOT attempt installation when the engine is hot.
• Disconnect the battery before installing wiring.
• If you need to cut and splice the wires, use the provided butt connectors and shrink tubing for a proper connection.

Design Intent:
• This kit is designed to operate electrical fan(s) in conjunction with an air conditioning system.
• To prevent damage to the A/C system the electric fan(s) should move air through condenser when the A/C is turned on.
• It is compatible with all vehicles and wiring harnesses. It can be used on a positive or negative ground 12 volt DC vehicle.
• This kit can be used with Be Cool Wiring Harness Kits #75021, #75032, #75098, #75100, #75117, or #75104.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vice where it will be as dry as possible and the least exposed to extreme temperatures.
Theory of Operation:
• The relay is actuated by power to the air conditioning compressor.
• When the relay is actuated one set of contacts closes the circuit to bypass the temperature sending unit.

Design Intent:
• This kit is designed to operate electrical fan(s) in conjunction with an air conditioning system.
• To prevent damage to the A/C system the electric fan(s) should move air through condenser when the A/C is turned on.
• It is compatible with all vehicles and wiring harnesses. It can be used on a positive or negative ground 12 volt DC vehicle.
• This kit can be used with Be Cool Wiring Harness Kits #75021, #75032, #75098, #75100, #75117, or #75104.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vice where it will be as dry as possible and the least exposed to extreme temperatures.
Theory of Operation:
• The relay is actuated by power to the air conditioning compressor.
• When the relay is actuated one set of contacts closes the circuit to bypass the temperature sending unit.

Design Intent:
• These wiring harness kits are designed to enable a simple and dependable installation for high performance electric
fan(s).
• They are compatible with all vehicles and can be used on any positive or negative ground 12 volt DC vehicle with no
modications.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vices where they will be as dry as possible and the least exposed to extreme temperatures.
Installation of the Temperature Sending Unit:
•DO NOT attempt installation when the engine is hot.
• The temperature sending unit is designed to mount in the intake manifold for the most accurate control of the system.
• The switch has 3/8”-18 N.P.T threads and will work in many applications. A 1/2” N.P.T. adapter is included in the kit if larger
threads are needed for this switch installation.
•DO NOT use “Teon” style tape on the temperature sending unit as this could cause a poor electrical ground and improper
operation.
• If you need to cut and splice the wires, use the provided butt connectors and shrink tubing for a proper connection.
See page 5 for installation instructions and pages 6 & 7 for wiring diagrams for
vehicles without air conditioning and pages 8 & 9 for vehicles with air conditioning.
Page 15
Design Intent:
• These optional high amp toggle switch harness kits are designed to enable simple installation of high performance elec-
tric fan(s).
• It is a universal t. It can be used on any positive or negative ground 12 volt DC vehicle.
• These switches can be used with or without a temperature sending unit using the diagram on pages 17 & 18.
• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vice where it will be as dry as possible and the least exposed to extreme temperatures.
Theory of Operation:
• When the temperature sending unit reaches its operating temperature it brings the attached wire to ground.
• When this happens the relay is “turned on” which, in turn, operates the electric fan(s).
• These manual high amp toggle switches serve as a bypass to the temperature sending unit and will operate the fans at
your desired temperature.
Installation of the High Amp Toggle Switches:
•DO NOT attempt installation when the engine is hot.
• Disconnect the battery before installing wiring.
• If you need to cut and splice the wires, use the provided butt connectors and shrink tubing for a proper connection.
See page 16 for installation instructions and pages 17 & 18 for a wiring diagram.

• The wiring harness is protected by many weatherproof components. However, care should be taken to position the de-
vice where it will be as dry as possible and the least exposed to extreme temperatures.
Theory of Operation:
• When the temperature sending unit reaches its operating temperature it brings the attached wire to ground.
• When this happens the relay is “turned on” which, in turn, operates the electric fan(s).
• These manual high amp toggle switches serve as a bypass to the temperature sending unit and will operate the fans at
your desired temperature.
Installation of the High Amp Toggle Switches:
•DO NOT attempt installation when the engine is hot.
• Disconnect the battery before installing wiring.
• If you need to cut and splice the wires, use the provided butt connectors and shrink tubing for a proper connection.
