Really good mod. They should incorporate your fix into their future product updates. 👍
Great video. Thank you for doing this.
Glad it was helpful!
Excellent work. Thanks very much for this video.
Thank you I needed to know how to wire it
thanks for the tutorial
Why not put the switch between the frame and the hose (above the on/off switch)?
Quick question for u? I added a pressure switch and it seems to work! however the compressor comes back on every 30 seconds or so for maybe 1 second. Is this normal? Or am I losing pressure somewhere? I thought once it reached the desired psi and was not in use it would stay off until I turned it on
Definitely from a pressure loss. Mine seems to do the same. It did when not hard-wired to the vehicle as well (with the pressure switch). Doesn’t bother me much as I usually have it off at the compressor unless I’m using it. Can’t help you much more than that unfortunately. 🤷🏼♂️
How long is the spacer adapter (1 x double female 1/4” NPT adapter) I like the pressure switch mounted here seems much better protected. Plus no stress on any of this once it together compared to being mounted in the back your always plugging and unplugging the hose. Nicely done.
Hey there. Thanks for the compliment. The female/female adapter is 1” long.

could you point us in a direction to find these fittings?
I found these fittings at my local hardware stores. I believe most are available at Home Depot but you can easily get them online on Amazon. They’re all pretty common. Good luck!
They could but it would drive the price up. It's priced well as is. Thing is I honestly don't see a need for this mod. Hook line up to tire, hit switch, stop when at desired pressure.
The reason to do this you don't have to run back and forth turning the compressor off and on at eash tire... also never a good idea to use the pressure safety valve as a switch.
