My high beams would not stay on because of an old relay that was just old. I did my homework, and this product fits and works I replaced my old OEM 4 Pin Relay 4F1T-14B192-BA, H8QTB that Ford no longer sells. great price

My 2019 Mazda Cx 5 HVAC bolwer fails to start runnig once in a while. Then it starts working again after sometime. It was a non repeatable problem. When it stops working, the blower would not run for all fan speed setting. When the blower is working, there is no noticeable air flow reduction, nor any kind of noise. I was the suspecting the relay maybe defective. This relay has 4 prongs and plugs into the relay port; however, the relay prongs are narrower and fit loosely. It did not work when I tested it. The blower would not run. The blower currently is running OK with old Mazda original relay. In summary, this relay probably will not work as a replacement relay for Asian cars. In my case, I bought Mazda OEM relay here from Amazon for $20. I would not now for sure yet if it solved the problem, until I drive the car for at least three months.

Perfect when adding 7 pin trailer capability to older Ford. Used to add the trailer battery charging and back up light power to Ford that had never had them installed.
