The LV Automotive 12V 4 Pin Waterproof Relay with Base handles switching on 12V setups where spray and dust are part of the trip. The four terminals marked 30, 85, 86 and 87 give you the standard layout you already know from workshop diagrams. You can run lights, compressors or other 12V loads while keeping the high current off the dash switch and wiring.

The relay body is sealed plastic and locks into the matching base with supplied green wire seals across all 4 positions. A metal tab with a hole of roughly 6 mm lets you bolt the kit to guards or brackets without fuss. The terminals are flat blades in plated metal sized for normal automotive female connectors. It is straightforward gear that suits Aussie engine bays from the bush to the beach.

Q: Can this relay be used outside the engine bay on a chassis rail?

Yes, the relay and base are built as a waterproof pair suited to exposed mounting points. The sealed plastic body and included wire seals help protect the contacts from road spray and mud. Just make sure the crimp terminals are fitted correctly into the base. A solid mechanical mount through the metal tab will help the gear handle vibration.

Q: Do I need a special crimping tool for the supplied terminals?

You need an automotive open-barrel terminal crimper that matches the style of the supplied female terminals. Proper crimping gives good mechanical grip on the conductor and insulation. That stops wires pulling out when the vehicle flexes. Good crimps also cut down resistance and heat at the connection over time.

Q: Is this relay only for LV Automotive harnesses?

No, the relay uses standard 4 pin terminal markings so it can be wired into many different 12V setups. You can integrate it into custom looms, light bar circuits or compressor wiring. Just follow the usual relay pin functions on 30, 85, 86 and 87. Always check your circuit ratings before final fitment.

Q: Can I mount the relay in any orientation?

Yes, the relay housing is sealed so orientation in normal automotive use is not critical. Many installers mount it with the tab upwards on a guard or bracket. A secure mount avoids vibration stress on the terminals. Keeping the harness supported nearby also helps the setup last.
