Review on 🔌 MICTUNING 12V 5 Pin Waterproof Relay Harness Set - Bosch Style Automotive 40A 30Amp with Heavy Duty Pre-Wired Harness 5 Pack by Carlos Melendez

These are the best relays I have used to date. The connector has silicone seals at the wire entries. and around the butt sliding into a relay with low skirts. The relays have a snap-on connection that provides a secure fit during assembly. They are designed for intensive use and I have had no problems with them. As you can see from the photos they are much larger than a standard heavy duty relay. Even the relay itself is larger and with the deep skirt and bulky plug it looks massive compared to the standard relay on the right. The only complaint I have is the length of the cord that goes into the plug. They are half the length of a standard relay connector cable. I cut the wires on the long relay connectors, but the shorter wires on the waterproof connector don't leave much room for splicing. I space the splices about an inch apart so there aren't a lot of splices to deal with wrapping wires. The staggered arrangement of the connectors makes the wiring cleaner and tidier. In general, they are worth their money.
