Regarding the installation of mechanical throttle, there are two ways of controlling the mechanical throttle car

  1. Use relay control fuel pump, so as to reduce the fuel supply of oil to the engine
  2. Use relay control solenoid valve that installed on the fuel pipe, so as to reduce pressure of the engine oil supplying.

The first way of installing the speed limiter

How to install the speed limiter on an electronic throttle car

The installation method is as shown, first one find the fuel pump power line, in the correct position to cut the fuel pump power line, the fuel pump power line (cut) near the engine side of the line connection relay 30 and 85, and the other end line of the relay 87a end line, the relay 86 end and the speed limiter white line connected. and wrap and secure it.

The way to control the solenoid valve is to connect the power line of the solenoid valve with the 87a line of the relay, and the solenoid valve is grounded by another wire.

The solenoid valve shall be installed away from the harness and the exhaust pipe.

In addition, please reconfirm that the speed limiter’s connector and speed limiter are securely installed.
