Most folks with real work trucks need their entire bed for hauling and capacity. Placing tanks and pumps in the bed eats up that precious space. Interior is out of the question due to excessive noise the pumps make. With a Frontier you probably don’t have to worry about these issues and therefore have plenty of room to mount in your passenger seat.

Thank you much for your input. I’ve always wanted an air compressor system for my pick up truck that has rapid recovery capability. The reason I put the system together is because there’s so many people out there on the freeway. They do not pay attention to what they’re doing. Usually they’re playing with the phone while driving down the road not staying in their own lane we all know what happens when your car gets wrecked. The value is diminished dramatically number one and number two it winds up in the shop to get repaired. It’s going to be there for a long period of time so I make sure that I have the ability to give them a loud wake up call to stay where they belong and away from my truck Also, it does not take me long to have 150 psi. I have run it up to 250 psi just to pressurize the system to make sure that it’s got no leaks Sometimes I use it to help others who have a flat tire and when I opened up the toolbox to connect my hose to inflate the tire, they are impressed with what they see The airhorns are in the grill you can’t see them unless you really look for them and I have them facing towards the ground. That way if I drive my truck through a car wash no water is going up inside of the airhorns I added another airline that goes up underneath the back of my truck so if I want, I can add a second set of air horns on the rear of my truck I’m sick of the stupidity on the freeway. That’s why I built the system that I put together .

Follow the diagram on the relay housing. Sometimes different vendors switch the pin numbers around.

​@@xcntrk75 yes sir. The diagram on my relay is identical to your relay in the video. When I activate upfitter 1, I hear a high pitched sound from the relay and my factory horn still sounds when pushed. Maybe the relay is bad. Two wires from the solenoid, one connected to 87 and is the second solenoid wire grounded? Thanks a lot for your time.

Agreed

Sounded good to me 😊

Ya that's what he has with the 3 batteries but it will wear out the motor faster but it's an easy mod but this video he's upgrading the motor

What check valve are you referring to? The fill system is integrated with the primary tank sending unit and will only fill the primary tank to 3/4 full then shutdown the transfer pump.
