Top Picks of Weatherproof Auto Relay

Can be easily installed in environments requiring waterproofing, such as pontoon boats and intercooler pumps.

Once installed, it will not easily disconnect due to vibration or pulling.

Align the plug with the socket, making sure that the rubber ring is not exposed. The connection is now complete.

We use pure copper to produce the wiring harnesses that we use as accessories.
Weatherproof Auto Relay
As a waterproof supplement to the FLS820, FLS820Q can be installed in areas of a car that require waterproofing.
