Nice 6 pack of bypass relay switches, these are helpful to diagnose bad relays or at least remove them from the equation as a problem. These won't fit everything, but if your pin layout matches one of these and the amp rating is equivalent, they're a nice to have.

This is a great selection of 4 and 5 pin relays that bypass the control circuit and jump the voltage from the supply pin to the load pin with only a flick of a switch. These make testing a circuit much easier and can also take the place of a bad relay when you're in the middle of nowhere.Each relay is marked with the continuous amp rating the relay can handle. Contains 6 types of relays in a nice plastic box. Good little kit to have around.

6Pcs 9038 Relay Bypass Switch Kit ReviewOverview:The 6Pcs 9038 Relay Bypass Switch Kit is designed as a replacement for the 9036 and 9037 fuel pump relay bypass kits. This kit includes six relay bypass switches and comes with a white compartmented storage box for organization. The primary use of these switches is to bypass the standard relay in various automotive systems, often for testing or troubleshooting purposes.Contents:6 Relay Bypass Switches: Each switch is designed to replace the 9036 and 9037 fuel pump relay and is suitable for applications where bypassing the relay is necessary.Compartmented Storage Box: A white box with compartments to keep the switches organized and easily accessible.Build Quality:Switches: The relay bypass switches are typically made from durable plastic with metal contacts. They are designed to be robust and handle the electrical load required for fuel pump systems.Storage Box: The box is constructed from plastic with a compartmented layout, which helps in organizing the switches and prevents them from getting damaged or mixed up.Functionality:Bypass Function: These switches are used to bypass the fuel pump relay, which can be useful for diagnostic purposes, such as testing fuel pump functionality or diagnosing relay issues.Compatibility: Designed to replace the 9036 and 9037 relay types, they should be compatible with various vehicles that use these relays for their fuel pump systems.Installation:Ease of Use: Installing the bypass switch is relatively straightforward. You simply replace the existing relay with the bypass switch to allow the fuel pump to operate continuously or for diagnostic purposes.Applications: Ideal for mechanics and automotive enthusiasts who need to test fuel pump systems or work on relay circuits. It’s also useful in situations where a quick bypass is needed.Pros:Complete Kit: Includes six bypass switches, which is convenient for multiple uses or for keeping spares on hand.Organized Storage: The compartmented storage box helps keep everything in order and protects the switches.Reliable: Designed to handle the electrical load required for fuel pump systems and other relay-based applications.Cons:Specific Use Case: Primarily useful for bypassing fuel pump relays; may not be needed for general automotive work outside of this scope.Plastic Durability: While durable, the plastic construction may wear over time with frequent use, especially under high-temperature conditions.Conclusion:The 6Pcs 9038 Relay Bypass Switch Kit is a practical and well-organized solution for automotive professionals and enthusiasts who need to replace or bypass fuel pump relays. With six switches included and a compartmented storage box, the kit offers convenience and reliability for testing and diagnostic purposes. It’s a solid choice for those working with 9036 and 9037 relay systems, providing an efficient way to manage fuel pump operations or troubleshoot relay issues.

As a professional automotive technician, I could have used these years ago. In the past I have bypassed relays by jumping terminals with a wire but these are much more convenient. The set comes housed in a clear plastic flip top box and includes 6 relays to cover many applications. Operation is simple by plugging in the relay and then using the on/off switch to operate. These can be very useful for fuel pump operation for various reasons. This is another inexpensive tool that is great to have in my arsenal. The quality is great and the price is very reasonable. 5 stars.

Good product! Worked great!

This is my dream come true to have these for automotive diagnostics! Now I can verify components are working without having to access the component itself. I can send power to it via this relay bypass. This is a real time saver!Update: they failed after 2 weeks of use.
