Introduction

The AFIS420VSX-B is a Fast Idle system that elevates engine idle RPM based on a number of “triggers”.
The vehicle must be in Park for Fast Idle to engage. There are three different engine RPM settings which
can be selected by grounding different control inputs. The three different RPM values can be independently
set during installation.

Options

AFIS420VSX-B — Single OBDII connector Data Link Harness

AFIS420VSX-BP — Two connector “T” Data Link harness

AFIS420VSX-BIP — Two connector white panel mount “T” Data Link harness

AFIS420-VSX-BW — Input 1 default speed is: 1500—RPM Gas/1500—RPM Diesel

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.

AFIS420VSX-B Module

Remove the lower dash panel below the steering column area and find a suitable location to mount the
AFIS420VSX-B module. Locate the module in an area away from any external heat sources (engine heat,
heater ducts, etc.). Do not actually mount the module until all wire harnesses are routed and secure. The
last step will be to mount the module.

AFIS420VSX-B Data Link Harness

1. Locate the vehicle’s OBDII Data Link Connector which is mounted below the lower
left dash panel.

2. Plug the Red connector from the AFIS420VSX-B Data Link Harness into the vehicle
OBDII connector. Ensure the connection is fully seated and secure with the supplied
wire tie.

3. Secure the AFIS420VSX-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 AFIS420VSX-B module.

AFIS420VSX-BP/BIP “T” Data Link Harness

1. Locate the vehicle OBDII Data Link Connector. It will be mounted below the lower left
dash panel.

2. Remove the mounting screws for the OBDII connector. Plug the Red connector from
the AFIS420VSX-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 AFIS420VSX-BP Data Link Harness in
the former location of the vehicle’s OBDII connector.

4. Secure the AFIS420VSXP-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
AFIS420VSX-B module.

AFIS Harness (8-Pin Connector) - Fast Idle Engage Inputs

Engage Input 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 “sense” of the Green wire can be programmed (see below). This alternatively allows equipment
which provides a 12V “active” signal to be connected to this input.

Engage Input 2

Attach the AFIS Harness connector Pin #7 White wire to any equipment that provides a ground signal when the
fast idle needs to be engaged. (PTO, pump, etc….)

Engage Input 3

Attach the AFIS Harness connector Pin #5 Yellow wire to any equipment that provides a ground signal when
the fast idle needs to be engaged. (PTO, pump, etc….)

If multiple engage inputs are active, the lower number has priority. Auto triggers will have the lowest priority
and will only trigger if none of the inputs are active.

Engage Input 1—Fast Idle Pin-8 Trigger, Active: Ground or 12V signal Enable/Disable

The module is configured from the factory for an active ground fast idle trigger. To change this to an active
12V trigger:

Turn the key on, place the transmission in neutral, apply the Service Brake, pull out on the Park Brake release
and apply the Park Brake four times within 5 seconds. Upon successful reprogramming, the LEDs will flash as
a confirmation. The user must cycle the key for the change to take affect. Repeat to reverse back to a
ground trigger.
