This is a relay that gets used almost daily, and it's held up remarkably well. The operation has been flawless, with no glitches or malfunctions to report. It's clear that this product was designed with durability and reliability in mind.
A standout feature of this relay and harness is its waterproof quality. It's installed in the wet bay of my RV, a location that can often be problematic for electronic components. However, the Waterproof Relay and Harness has faced no such issues. This feature gives me confidence that it will outlast the original relay, which wasn't waterproof and failed prematurely.
If you're in need of a durable and waterproof relay and harness, I highly recommend this one.
I used on a motorcycle under the faring to control fog lights ... It will likely be drenched during any rides in the rain and if I had used a standard automotive relay I would never have been able to make it as waterproof as this is with heat shrink tubing etc etc ...
Highly recommend ...
Also on a side note I appreciate the wiring diagrams in the item description. I have zero auto electrical knowledge but wanted to wire fog lamps up in parallel to my headlights but didn't want the lights drawing power from my headlight switch, so I T'd the power of this relay off the headlight lead and now only the relay draws power from it, as opposed to both fog bulbs. It's much much safer and should prolong the life of an expensive 45-year-old light switch.
I will almost surely buy another of these when I add another external accessory.

First, in an earlier review a user commented that the plug was hard to plug into the relay. He is correct but solution is simple. Add a drop of dielectric grease to each terminal. Two things happen. You increase the water resistance and two your plug will glide together easily.
Second point. I had two items I wanted to power from the relay. Hence I bought the five wire with two outputs. Terminal 87 and 87a. Unfortunately I learned something. Terminal 87 is on with the relay triggered as advertised. Terminal 87A however is opposite. It is “hot” when relay is off. It was an easy fix but this is where a wiring diagram would have been nice. FYI. Terminal 30 is fused power. 86 is the trigger and 85 the ground.
One thing I'd did though was to add some dielectric grease on the connector before I plugged in the relay for some extra piece of mind.
