Review on 🚗 Wolo 8088-C 12V Universal Compressor Replacement for Direct Drive Horn (18-21 PSI) by Dawson Schmidt

In this upside down world, this is a great product. I mean once I figured out that they hooked it up the other way around it works great. The old pump on my horns is tired. It's embarrassing to honk the horn and your truck sounds like a cartoon hauler. The new pump is a few kilos bigger and is now waking up the neighbors again. I just can't give 5 stars, how does a plus wire become a minus and a minus become a plus?
