ONLINE LED STORE TRUE MODS 1 Pack 5-Pin 12V Bosch Style Waterproof Relay Kit [Harness Socket] [12 AWG Hot Wires] [SPDT] [30/40 Amp] 12 Volt Automotive Marine Relays for Boats Auto Fan Cars

This is a really nice heavy duty relay. I put it in my 2017 Superduty to run my auxiliary backup lights with my upfitter switches. With this relay installed I can run the auxiliary backup lights in two modes, ON when ever I want (even with the truck OFF) or make them go ON and OFF with the factory back up lights. Works great and I didn’t have to use a diode. My configuration uses two of the upfitter switches in the truck. The mounting bracket worked out nice. This relay is water proof as well, has a nice ribbed torturous path gasket. 7/16/20 Update: Two years now and still working, no issues. Thumbs up! 7/25/2023 Still going strong! 05/21/24 still working!!! I bought two of these on my original purchase, one as a spare because that’s what I do. The spare is still sitting on the shelf in my basement.

good quality product saves a fortune using this with transistor and some wire. Cheap fix bi passing startup air mix removed all warning lights and got truck out of limp mode.Youtube is a lifesaver!

Great Product and fast shipping. Thank you!

I am not a professional car electrician, but I have quite a lot of knowledge regarding this matter. I wanted a supplementary USB port working on A position ignition switch mode with some switch-off dellay. A relay is imperative in order to avoid too much power consumption and loss. For sure, using a waterproof system is always preferable in cars. Online LED store offered exactly what I needed and the system is working flawlessly. I am very pleased with their offer and I had to order it again, since my friends are putting a lot of pressure on me in order to make this port for their cars too. The only thing I had to modify was the gauge of the connected wires because the original comes with a low gauge number, which is too thick for a low consumer. With a little bit of effort it's possible to do the job, but I think it will be much nicer to supply the relay with the necessary contacts only, letting the customer to decide what wire gauge is fit for a specific job. Great value for the money. Prompt delivery.

Outstanding module, this was able to quickly and efficiently help me wire a new horn to my truck safely. Would buy again.
