thank you sir! wasnt bad to install either... had to take the pillar down... and run a yellow wire from the air gauge to the battery.. cause it monitors system voltage, a green wire to the sender on the tank, and had to buy an adaptor from ace for the 1/8th sender, black to ground, red to power. then you gotta take the ground off the sender and ground it to the same place as the gauge ground, for accuracy purposes. took bout 30 mins.. cause i was makin it all look clean down the frame rail, cause the tank is in the toolbox with the compressor!
