4 Light, Quint and Mark 5 - Installation Instructions
Locate a position on the pump panel for the display module. Decide if the unit is to be front
mounted or behind the panel mounted.
If the display module is mounted BEHIND THE PANEL, cut an opening using the following
4 Light - 3 3/4" high x 1" wide
Quint - 4 5/8" high x 1" wide
Mark 5 - 5 1/2" high x 1" wide
If the display module is FRONT MOUNTED, cut an opening using the following dimensions:
4 Light - 4.22" high x 2.45" wide
Quint - 5.15" high x 2.40" wide
Mark 5 - 5.769" high x 2.40" wide
Power is supplied to the 4 Light and Quint display modules through (2) #18 gauge wires, red
to power and black to ground.
Power is supplied to the Mark 5 display module through (4) #18 gauge wires, red to power,
black to ground, orange to power, forward of the master switch and brown to "optional"
remote audible or visual alarm.
Units are for use with a negative ground and therefore should not be used on vehicles with a
positive ground system.
Control cable and power supply wires exit out the bottom of the display module. Front mount
unit is supplied with the front mount bezel and (4) #8 self tapping screws.
The display module has approximately 3' of cable exiting from the bottom. The sensor has
approximately 8' exiting off the flange. Route the cabling through the truck and connect the
two connectors firmly together. Additional control cables may be ordered if needed.
Sensor should be located in the deepest part of the tank (but not in the sump, or where it
could be affected by the swirling action of the water leaving the tank, or in direct line of the
discharge of the tank fill opening).
If sensor is too long for the tank, cut to length following instructions in the field sizing
Sensor requires a 1 1/2" opening in the tank.
(4) - 1/4" holes in a 2" bolt circle are required to install the sensor. When laying out the bolt
holes, be sure that the cable exits from the flange in the direction intended.
