Step 6: Install Park Brake Safety Switch
Locate parking brake line behind the dash. This line is a 3/8
th
size air line. Cut parking
brake hose a minimum of three inches from valve and insert brass Quick-connect T
fitting on each end of cut line. Once switch is installed, make sure the vehicle air
system has adequate air pressure and depress valve to verify no leaks. Connect Idle
Smart’s yellow-sheathed wire to the connector at the end of the Quick-connect T
fitting. Reapply parking brake.

Step 7: Connections to Ignition System
Run the red, white & blue sheathed wires to the ignition system. Use a test light to determine the correct wires on
the vehicles ignition system and connect the following Idle Smart wires using the Sealed Crimp connectors:
•
Idle Smart yellow wire to battery 12V+ side wire on ignition switch;
•
Idle Smart brown wire to ignition accessories side of switch;
•
Idle Smart green wire to ignition power side of switch;
•
Idle Smart orange wire to start signal (crank signal) wire.

Step 8: Connections to Increase RPMs
The Idle Smart standard installation is to increase the idle RPMs by connecting to the cruise control documented
below. Idle Smart will be installed to either the cruise control or to the PTO but never to both. Some applications
require Idle Smart to connect to the PTO. In this case, Idle Smart will provide notification for PTO installations.
Otherwise, cruise control should be the default installation.
- Connecting to the Cruise Control:
Locate the sets of orange/black and yellow/black wires in the black sheathing. These wires are to be connected to
the cruise system as follows (cruise control must be off to work correctly):
•
Idle Smart yellow wire to cruise on signal side of cruise on/off switch;
•
Idle Smart orange wire to idle increase signal, on cruise set resume switch;
•
Idle Smart black wire is unused for this application. Coil and stow.
- Connecting to the PTO wire:
This option should only be used after prior notification from Idle Smart. Prior to installing per this option, the PTO
setting must be enabled through the ECM and access wiring for the PTO installed.
Locate the yellow/black wires in the black sheathing. These wires are to be connected to the PTO as follows:
•
yellow wire to the truck’s PTO signal wire. PTO signal wire must be identified and enabled, ECM must be
enabled and configured to engage correctly.
•
orange wire is unused for this application. Coil and stow.
•
black wires are unused for this application. Coil and stow.

Step 9: Install Neutral Safety Switch
(This step can be skipped for vehicles with automatic and electronically shifted
transmissions. In these vehicles simply plug the Idle Smart small connector (with
the wire loop) to the green and yellow-sheathed wire and stow neatly in the dash)
Locate the green and yellow-sheathed wire for the Neutral Safety Switch. Connect
the green and yellow Idle Smart extension to provide the necessary length of wire.
Run this wire through back and bottom of the dash and through the gear shift boot
cover. Locate the Neutral Safety Switch plug on top of the transmission housing.
This plug position varies with transmission manufacturer but the transmission will
say “Neutral Switch” at the correct plug location. Remove this plug and replace with
the provided Neutral Safety Switch. In most cases, both metric and standard threaded switches are provided by Idle
Smart to accommodate the switch installation on various transmissions. Connect wiring to switch connector.
