Relay for BMW Serie 3 - E21

12 Volt DC relay with 4 laminated terminals, 30/40 A

Universal relay for auxiliary equipment. Ideal for supplying current to an electrical device that is particularly far from the switch and battery, it can boost the starting performance of your old car, for example, by reducing the length of the wiring harness between battery and starter. Placed as close as possible to the starter, the original contactor controls the relay, which in turn gives the impulse to the starter with a minimum loss of current. For 6-volt circuits.
