ISO Mini Relays are the most common relays used in older vehicles or for general aftermarket automotive applications. ISO Mini Relays are available from Hella, Bosch, TE Connectivity (formerly Tyco), Littelfuse, Hongfa, HKE, and more.
Most modern vehicles have moved to smaller relay systems such as the ISO Micro Relay.
Available in many configurations, the most commonly available are the 4-pin SPST and the 5-pin SPDT (often called Bosch Style Relay).
