🚗 ESUPPORT Car Truck Motor Heavy Duty 12V 40A SPST Relay Socket Plug 4Pin 4 Wire Waterproof Seal Pack of 5 - Guaranteed Performance and Durability Review

Used in my LS3 wiring harness. I used two relays to power my two 40 amp SPAL 1650cfm fans, no problem. My only concern is that they don't go together to fit better.

Looks very good. Reliable and tight. Must not leak water. I wish each had a GA wire or description in the listing but overall good value for money.

I haven't actually tested them in the water but upon visual inspection they seem to be of really good quality. When I bought it, my biggest concern was that the cables wouldn't be long enough or wouldn't fit. be interchangeable, but they have been perfect for my use so far.

I gave them 3 stars because they seem overpriced and aren't really 40 amp relays. They are made overseas so be aware. However, they have been working on installing low power LEDs and I am happy with them so far. The quality seems really good and they appear to be waterproof as advertised. NOTE: They are delivered without brackets!

The relay sent does not match the one in the photo. They are advertised as not including a mounting tab/bracket so I ordered the tabs based on the photo. The relays that came out use more Hella type mounting tabs so I'm stuck with 10 tabs that don't fit and 5 relays that I can't install. I recommend looking elsewhere.

2 out of 5 I have already installed and work fine. Very satisfied. Visual inspection revealed no defects. When switched on, the coils all sound the same. I will update if one of them fails or if all 5 are as reliable as their apparent quality shows. I use them to switch LED light strips to run far from the 40 amps they are rated for. They must be operated at less than 50% of their rated power for life. It is worth buying and buying more.
