And ive added the compressor on the trunk and the 4 horn on the front and the valve is also on the front, but 1 of the 4 air pipe from the valve to horn is about 1 inch longer, does it matter?
Anyway, i suck at wiring electronic, i got no idea what to do with the wiring, what i was thinking to power compressor is.
Battery->30a fuse->switch from the package-> compressor?
But i got no clue about how i can connect the valve it has 2 grey wire, and how i can trigger the horn.
Im starting to think that i may have to buy a switch, or maybe i can use the steering wheel horn button?
Dont know either how i can acess the wire from outside to inside the car.
What kind of car? Knowing this will help with what you need to power the compressor.
For the horn valve, a simple push button is fine. Run power from a fused location in the car to the button, then out to the horn valve. Ground the horn valve and you’ll have the first circuit done.
For the compressor, you’ll need something heavy duty. I’d recommend 1/0 welding cable since it’ll take some abuse and will easily handle the load. Double the length to get both positive and negative to the battery. Since the tank and compressor should be close, run a piece of smaller gauge wire from the positive cable off the battery to the pressure switch and you’ll be done there.
Make sure it works and you should be ready to start honking!
You only need one wire ran for the compressor as you can ground the compressor where you have it located.
I ran 2 switches into my dash, one to power the compressor and the other to switch the horn on/off so I can control it through my regular steering wheel button.
The airline lengths are not an exact science. As long as they’re within a few inches of each other, they’re good.
Wire came with the kit for the compressor, didn’t it? It’s not the heaviest stuff, but it’ll do. Anyway, here’s a diagram from Viair. Even they’re lightest duty kit - they show a relay. http://www.viaircorp.com/OffRoad/Schematics/10000_wd.pdf
Your way will work, but I’d use a relay and use an ignition source for the trigger wire. That way your compressor can’t drain your battery while the engine is off.
It’s a good idea to fuse any wire coming off the battery. Either gray wire can be the ground.
Do you have the owners manual? Or there’s probably a diagram on the fuse panel door. Look for a fuse that says IGN or something. Or you’ll have to use a voltmeter or test light to find one. Then buy a fuse tap like this:
The pressure switch is probably already installed on your tank. It makes sure you don’t overpressurize the tank. You really should use it and the toggle switch. The toggle switch would be the master cutoff switch if you put it between the ignition source and the pressure switch.
Look for existing rubber grommets in the firewall. And rubber plugs in your trunk floor. If you can’t find any or they’re not in a good spot, you’ll have to drill a hole and use a new grommet.
Yeah the pressure switch is already on the compressor.
And i found a place to place wire inside.
Also, i tried connecting the air cable from the compressor from the trunk to the vavle in the hood, its not long ennuf, is there a place where i can buy compressor cable in a hardware store or something?
I beleive that the air line to connect to the compressor is
17 ft of 1/2 in D.O.T. Approved Airline
Right? Im gonna need nearly 25 ft just to be sure i have enuf.
Any parts store could set you up with some fittings and hose. You could buy some 1/2 or 5/8 hose with a few barbed fittings and run that to where you need to go.
I cant get the fancy push connectors that HB has here locally, but was able to wire up all the rest of my system with the regular barbs and fittings from a local parts store.
Local hardware stores usually have plain rubber air hose. It works fine, but you have to buy barb fittings. Your push-to-connect (PTC) fittings are meant for nylon DOT tubing. Probably won’t find it locally without a bunch of searching.
Are you splicing into the wire or using a fuse tap like I posted above?
If you use the add-a-circuit you use the original fuse and your own new fuse for your new circuit. 5 amp is plenty for that trigger wire. You can use cheap 18ga wire.
If you want to splice into the cig lighter use at least the size of the existing wire (14ga?) since it is ultimately fused with 15 amps. If you want to use cheaper 18ga wire you should add an inline fuse of 5 amps.
