HOW TO USE BREAKER BOX

The engine control module (ECM) and other connectors
have water proof connector and special terminal. Water
proof terminal does not allow to use back prove. In
addition, the engine control module (ECM) special
terminal can not let regular digital voltage meter prove
to access, because terminal shape is very fin pin type.
In order to prevent damage of female terminal and
connector itself, the breaker box and adapter is the
most suitable special tool.
