□
Step 1: Place vehicle in safe condition
Park vehicle on flat, safe area and chock the wheels. Be sure to secure any safety devices on the hood to prevent
accidental closing. Remove key from ignition switch and set cruise control to Off. Be sure to wear safety glasses
and use personal safety protection equipment when working around vehicle batteries and/or using power tools.
□
Step 2: Verify CanBus Information
Verify that the truck has J1939 protocol installed,
which is required for Idle Smart to work. To verify
that the truck will work with Idle Smart, pins must
be included in C and D on the 9-pin connector.
This connector is usually located below the dash
next to the brake pedal. On pin A, notice the key
notch that will help to identify the correct location
of the other pins. If pins are not present in C and
D, Idle Smart will not work correctly. Abort the
installation and call Idle Smart.

Step 3: Place Base Unit
Remove dash cover to find an appropriate location to place the Base Unit. This
should be near the parking brake line behind the dash. The Base Unit should also
be near a 12VDC power source, and close to a flat surface or area for mounting or
securing behind the dash. Do not mount or secure the Base Unit until later.
□
Step 4: Connect Power
Locate Base Unit power and ground wires, the red and black wires in red sheathing. Connect to 12VDC battery
power source within dash. Connect the red wire to the 12V+ source that is direct and has constant power. Connect
the black wire to ground.

Step 5: Install Hood Safety Switch
To install the Hood Safety Switch, find a mounting location such that when the hood is closed, the hood tilt switch is
vertical. When the hood is fully open, this switch should rotate slightly past horizontal. This switch is usually
mounted on a flat surface next to the rear of the headlight on the hood. To attach the hood switch, secure the hood
switch with the enclosed screws, epoxy putty, or use both for extra strength. Attach the hood switch with the
connection wire at the bottom of the switch. Thoroughly clean the mounting areas with the enclosed alcohol wipes
before applying the epoxy putty. To activate the epoxy putty, simply knead the material and place a small amount to
the base of the switch, attach to vehicle surface, and apply pressure for 30 seconds. This epoxy takes one hour to
properly cure. After switch mounting, locate the green-sheathed wire on the harness. Run this wire through the
firewall and connect to the wired half of Hood Safety Switch. Secure wiring to truck frame. It is recommended to run
the outside temperature wire through the firewall at this time along with the green-sheathed wire to save time on
step 12 (See step 12 for instructions for this wire).
