Pull out the car relay and insert it into the slot to fix it. -2.This product is equipped with a dedicated amplification loop that can seamlessly match with clip on amplifier probes to accurately capture changes in circuit current.

  • Stable Material: This product is made of high-quality nylon and copper materials. This product has good stability performance, which can effectively resist the complex conditions inside the car engine compartment, avoid aging and damage, and extend the service life. The pins are made of copper material, which has good conductivity and can reduce losses during current transmission, ensuring stable and smooth circuit connections.
  • Widely Used: This product has strong versatility and is widely applicable to most automotive equipment. Whether it's fuel pumps, cooling fans, window motors, headlight switches, or air conditioning compressors, any device that uses automotive relays can be easily adapted for use. No need to worry about device model matching issues, suitable for various scenarios such as maintenance and testing, temporary control, etc.
  • Easy Installation: The product adopts a plug and play design, and the installation process is simple and efficient. It supports both vertical and horizontal installation methods, without the need for professional skills and complex tools. Simply locate the position of the fuel pump relay on the vehicle, remove the old relay, align the copper feet of this product precisely with the slot and insert them, ensuring tight contact. The entire process is quickly completed.
  • Independent Control: This product does not rely on the vehicle key switch system and can directly control the fuel pump independently, greatly simplifying the fuel injection testing process and improving the convenience of maintenance and debugging. At the same time, it come with an amplification loop that can be used in conjunction with clip on amplifier probes and laboratory oscilloscopes to accurately monitor circuit current, help quickly troubleshoot faults, and optimize circuit parameters.
  • Scope of Work: This product is suitable for 12V automotive circuits and supports 20 ampere continuous current and 30 ampere surge current. Various types of automotive 12V DC motors can be easily driven by flipping the switch. When the car relay suddenly malfunctions, quick access can immediately restore the normal operation of key equipment such as fuel pumps and cooling fans.
