BT1-0700 Low Pressure Switch Harness Assembly

The BT1-0700 Low Pressure Switch Harness Assembly is used in mobile A/C electrical systems.
It connects the low pressure switch to the system wiring.

This harness assembly cross references with MEI 1526 and AirSource 1526.
It also fits several related switch applications, including 1419, 1430, 1512, 1513, and 1516.

As a result, it is a useful replacement harness for compatible heavy-duty mobile HVAC systems.

Function and Performance

A low pressure switch helps protect the A/C system.
It can interrupt compressor operation when system pressure drops below the intended range.

The harness assembly provides the electrical connection for the switch.
Therefore, a clean and secure harness connection is important for proper switch function.

Because switch harness fitment depends on connector style and switch compatibility, compare your existing harness before ordering.

Durability and Design

The BT1-0700 harness assembly is designed for mobile HVAC service.
Heavy-duty truck and equipment systems often face vibration, heat, dirt, and moisture.

This harness is intended for compatible low pressure switch applications.
In addition, it may be used when replacing or servicing supported switch numbers.

Always verify the connector, lead style, switch number, and system wiring before installation.

Installation

Install this harness according to the vehicle or equipment service procedure.
Before installation, inspect the low pressure switch and wiring connection.

Confirm that the harness fits the switch and system connector.
Also check the A/C system for proper refrigerant charge and pressure conditions before returning the unit to service.

If the old harness shows corrosion, damaged terminals, or broken insulation, inspect the surrounding wiring as well.
