relay 30a

Good Day! First of all I'm a junior so take it easy with me, I'm doing my best as well as I can :) I bought a new local Central Locking system for my car to replace the old one, The new one has only 4 actuators for doors and I already have one actuator for the trunk which has two terminals...
