Accessory relay 12V/ 40A , suitable for a wide range of applications, all vehicles, for headlights, rear window defrosters, air blowers…

Description

Also a relay for the refrigerator’s rear air distribution unit

Relay for fog lights, parking lights, and driving lights.

Relay for high-volume horn

This power relay ensures a stable power supply by minimizing voltage drops caused by the wiring harness and electrical contacts. Because of how it operates, the switch controls only the relay coil, which significantly reduces premature contact wear.

When replacing an original equipment relay, it is important to check the number of terminals and the connection configuration to ensure compatibility with the relay installed in the vehicle.

This relay can replace the original equipment on many classic Volkswagen models, but it is also recommended when installing high-power electrical equipment such as auxiliary headlights, fog lights, dual horns, or heating systems. For any installation of high-power accessories, the use of a dedicated relay is strongly recommended ⚡

A small detail that saves hours of electrical troubleshooting 😅: a worn-out relay can cause subtle but very annoying voltage drops, especially on older VW wiring harnesses.
