Finally got a set of horns on my Tahoe 
K3HA
Two five gallon tanks
Dual 480c
Very nice and clean looking install.
nice, what PSI you running?
max is 200 but i usually just charge it to 100 for every day driving and its still plenty loud. but if im goin out to scare people ill fill it up to 200
Nice job! Why not compromise and set the pressure to 150 all the time?
well i always say… Go big or go home. hahaha so yah i know i probably wont get it that high to often but its great to have the versatility and the ability to without needing upgrades.
That horn button is SICK!
my horn button is my cigerette lighter
gives a new meaning to Lightng one up! 
Nice install! I’m familiar with that interior & I like the gauges/switches & button.
The wires on the leader hoses - Are those the pressure sending units for the digital gauge? If the reading bounces around a lot while the compressors are running, moving them back to the tank would help.
Both tanks will collect water. You could easily move the safety valve to the front of the tank and put a drain valve there instead.
Everything looks great.
those are temp sensors. being that i live in Arizona, it very hot about 6-9 months out of the year, so i had this idea to put sensors on them. Even thought the compresses have a shutoff when it gets too hot i would like to detect it before then. for example today without even running them they were sitting at about 110-115 degrees and its only February. so far the sensors read fairly accurate except for my middle gauge is reading off of a bad sensor. Im getting a new one soon.
