works great
The heavy duty connector made it easy to install and holds pins in place. using on a truck light bar

Great Relays
Used these to install some LED raptor lights on my two trucks. Very easy to install and no issues. Directions were clear enough for my first time using relays. Great price for two of them. Would buy again if needed for future projects.

Congo Tested - Replacement for Smittybilt 2781
Used this to replace the burnt out relay on our 2781 compressor. Just fit and working great

Bigger than the normal relays
These are big. I did not know that 2 of the blades would be extra large and not just a replacement relay. I had to it wire in with the supplied harness. Luckily 2 of the pins I just pushed out and swapped over to this new one, but the large power pins prevented me from just changing to the relays.

Works fine
Hooked up two puller radiator fans through one of these. It fit the bill.

Heavy duty 80 amp relay - same size as 30/40 amp relay
I really just needed the harness since I'm a mechanic and already have 80 amp relays, but it was about the same price to get the relay with the harnesses.Photos show coil amperage draw at different voltagesMinimal voltage to active coil is 6.7 voltsLowest voltage that will keep coil activated is 4.9 voltsLast two photos show this relay (right) next to a standard 30/40 amp relay. It is physically the same size, but the switched contacts are much larger to handle higher amperage. These are the same relays that typically run radiator fans in most vehicles.

Worked great in my 91 Miata for the ACC power.
I ran a line from ACC (where the radio was) in my 91 Miata and use it to turn on a bunch of other circuits. This thing worked fine.
