Engine Hatch Actuator Relay BoxMany manufactures ran all the amperage thru the switch which creates a voltage drop slowing the actuator and making it weak. This kit when installed gets voltage from the battery and only uses the switch to trigger the relays allowing more voltage to go to the actuator. This kit is easy to install, a few connectors, a fuse or breaker, and maybe a little wire and your actuator will act like brand new. The case is waterproof so water is not an issue.
