Overview

The Advanced Fast Idle System (AFIS) elevates engine idle speed in response to a number of triggers in
order to assist electrical or mechanical systems on the vehicle.

Options

AFIS422VSX-B — Single OBDII connector Data Link Harness

AFIS422VSX-BP — Two connector “T” Data Link harness

AFIS422VSX-BIP — Two connector white panel mount “T” Data Link harness

Installation Instructions

Disconnect vehicle battery before proceeding with installation.

IMPORTANT—READ BEFORE INSTALLATION

It is the installer’s responsibility to route and secure all wiring harnesses where they cannot be damaged

by sharp objects, mechanical moving parts and high heat sources. Failure to do so could result in damage

to the system or vehicle and create possible safety concerns for the operator and passengers.

Avoid placing the module where it could encounter strong magnetic fields from high current cabling

connected to motors, solenoids, etc. Avoid radio frequency energy from antennas or inverters next to

the module. Avoid high voltage spikes in vehicle wiring by always using diode clamped relays when

installing upfitter circuits.

AFIS422 Module

Remove the lower dash panel below the steering column area and find a suitable location to mount
the AFIS422 module. Locate the module in an area away from external heat sources (engine heat,
heater ducts, etc.). Do not mount the module until all wire harnesses are routed and secure. The last
step of the installation is to mount the module.

Data Link Harness (4-Pin Connector)

1. Locate the vehicle’s OBDII Data Link Connector , mounted below the lower left dash
panel. Plug the Red connector from the AFIS Data Link Harness into the vehicle OBDII
connector. Ensure the connection is fully seated and secured with the supplied wire tie.

2. Secure the AFIS Data Link harness so that it does not hang below the lower dash and
plug the (4-pin connector) from the Data Link Harness into the 4-Pin connector on the
AFIS module.

AFIS422VSX-BP/BIP “T” Data Link Harness

1. Locate the vehicle OBDII Data Link Connector, mounted below the lower left dash
panel.

2. Remove the mounting screws for the OBDII connector. Plug the Red connector from
the AFIS422VSX-BP Data Link Harness into the vehicle’s OBDII connector. Ensure
the connection is fully seated and secure with the supplied wire tie.

3. Mount the Black pass through connector from the AFIS422VSX-BP Data Link Harness
in the former location of the vehicle’s OBDII connector.

4. Secure the AFIS422VSXP-B Data Link harness so that it does not hang below the lower dash
and plug the 4-pin connector from the Data Link Harness into the 4-Pin connector on the
AFIS422VSX-B module.

AFIS Harness (8-Pin Connector) Fast Idle Engage Input, Green wire

1. Attach the AFIS Harness connector Pin #8 Green wire to any equipment that provides a

ground signal when the fast idle needs to be engaged. (PTO, pump, etc.). Note: The
Green wire can also be connected to equipment providing a 12V signal, if programmed.
See below for programming instructions.

2. Plug the 8-pin connector from the AFIS Harness into the 8-Pin connector on the module.

VBAT Low Fast Idle Trigger Disable— Black wire loop

The system is configured from the factory for Fast Idle to be triggered when the battery
voltage (VBAT) drops below 12.5V. If the VBAT Low Fast Idle Trigger is not desired, it
may be disabled by cutting the Black wire (loop) on the 8-Pin connector between Pin #1
& Pin #3.

Configurable Idle Speed - Gray wire

The AFIS422VSX-B allows the user to change the fast idle RPM during installation. The default speed is
1500 RPM gas / 1200 Diesel, but the user can select any speed between 900 RPM and 2000 RPM in 50
RPM increments. To change idle speed:

1. Locate the Gray wire in the harness which connects to the 8 pin Molex connector.

2. Pull this wire out of the loom to expose the bare copper end.

3. Place the vehicle in Fast Idle by grounding the Manual Trigger Green wire. With the engine
in Fast Idle, momentarily grounding the Gray wire (RPM Configuration input) increases the
idle speed by 50 RPM. When the idle speed reaches the maximum allowable speed for the
particular engine, it will roll back around to 900 RPM. Wherever the user stops, this RPM
becomes the new default Fast Idle speed, even through key cycles.

4. After the vehicle is set to the desired fast idle speed, insert the end of the Gray wire into the harness tubing
and use tape to secure.

Note: Some vehicle PCM’s will limit Fast Idle to less than 2000 RPM. Continue momentarily grounding the
Gray wire and the RPM will eventually roll back around to 900 RPM. Do not leave the RPM’s set in a range
that the engine RPM is not responding to, as this may cause Fast Idle issues.
