OWNERS MANUAL
Model ETM51
Electronic Throttle Module
for
2005+ Ford Gas & Diesel Engines
Introduction
Model ETM51 Electronic Throttles are designed to support 2005+ Ford trucks and
vans equipped with the Ford Stationary Elevated Idle Control (SEIC) and one of the
following engines:
6.4 Liter Power Stroke Diesel 6.8 Liter Triton Gas
6.0 Liter Power Stroke Diesel 5.4 Liter Triton Gas
6.7 Liter Power Stroke Diesel 6.2 Liter Triton Gas
Modules come with four modes of fast idle control: Three user-adjustable preset
speeds and one variable input based on a remote variable resistor. The ETM51
installation requires customer-supplied control wiring to select the required mode of
operation and to connect to the Ford SEIC wiring. Ford provides blunt-cut wires, and
these may be connected to the ETM51 module via 0.25 inch Faston blade terminals
(may require extensions of the wires).
The ETM51 kit includes a three foot data cable with a 16-pin connector plug for the
OBDII data link connector (DLC) on one end and two faston terminals at the other.
The DLC is usually located at the lower part of the dash on the driver’s side.
Operation
When the vehicle is parked and Chassis Ready Conditions are satised, the engine
idle speed may be controlled by selection of one of the four available modes: three
presets and one variable RPM. The preset RPM modes may be adjusted via three
calibration potentiometers on the top of the ETM51 unit.
Chassis Ready Conditions
1. Parking brake is set
2. Gear shift lever is in PARK (automatic only) or NEUTRAL (F750)
3. Foot is off the service brake
4. Foot is off accelerator pedal
5. Vehicle is stationary
6. Engine is started and idling below 900 RPM
7. Coolant temperature >140°F (Gas), 120°F (Diesel)
8. Transmission temperature 20°F to 240°F
Supported Through
the 2019 Model
Year Only!

ETM51 Owner’s Manual
Important Note:
While the engine is in high idle, should one of the Chassis Ready Condition inputs
change state, the engine will return to normal idle speed.
In 2010 and earlier diesel engines, if the Chassis Ready Condition input is restored
to satisfactory conditions, the engine will automatically return to fast idle after three
seconds. However, in gas and 2011 and later diesel engines, the engine will not
automatically return to fast idle. Instead, the Ford SEIC must be manually reset
by turning the Fast Idle switch off and then back on. With ETM51 revision H and
later, software will auto restart diesel engine high idle whenever chassis ready
conditions are correct. NOTE: For 2 wire Gas PTO Interfaces on the 2011-2016
F-Series, the ETM51 will require the addition of an optional relay circuit
shown on page 16 to automatically restart the PTO.

Optional Variable RPM Mode:
Function: Varies RPM as a function of voltage on the VRPM input
terminal
Terminal: VRPM
Adjustment: 10K Ohm potentiometer between the VRPM terminal and
ground
Enable: Turn potentiometer down to zero resistance, then slowly
increase until desired RPM is reached
Disengage: Turn potentiometer down to zero and RPM will drop to
standard idle speed
RPM Range:
Gas: 900-2250 RPM
2005-2010 Diesel: 1200 to 2300 RPM
2011+ Diesel: 900 to 3000 RPM

* The Ford Powertrain Control Module (PCM) High Idle is not active and indicates one or more
of the SEIC ready conditions are not being fullled.
Installation
1. Getting Started
We recommend installing the ETM51 system under the dash due to the proximity of
the wiring connections and cable length. The unit should not be located in the engine
compartment or any other location that is not protected.
You will need a crimping tool for the 0.25 inch Faston blade terminals and a wire
stripping tool. Be sure to follow the crimping tool instructions for the proper wire size
and terminals. Do not lengthen the DLC Cable. Disconnect the battery before making
any electrical connections.
WARNING!
Do not connect any 12 volt power source to the ETM51’s PTO terminal wiring.

2. Mounting
Mount the ETM51 Module under the dash or on a at surface using the two mounting
holes. Ensure that you have sufcient distance to install the 36 inch DLC cable.
3. Installing the DLC Cable
Connect the two Faston terminals on the DLC cable to the ETM51 module terminals
(Yellow wire to CANH terminal and Green wire to CANL terminal). Route the cable to
the OBDII Data Link Connector and plug it in. The OBDII connector is usually located
on the lower part of the dash on the driver’s side. Using a cable tie, secure the plug
to the OBDII connector so that it will not vibrate out. We recommend routing the DLC
cable across the bottom of the plug/connector and looping the cable tie around the plug,
socket and cable to keep it out of the way.
4. Wiring the Mode Selection and SEIC Controls
The ETM51 module must be wired to the Ford SEIC blunt-cut wires and to the customer-
supplied Mode Selection controls. The wiring is different for diesel and gas applications,
so please refer to the appropriate wiring diagrams on pages 6 through 16. You will also
need a good quality chassis ground (battery negative) signal and a +12 volt supply fed
from the Ignition Switch.
Note that on gas engine installations, Ford requires the +12 volt supply to be
“clean” - i.e. it should have no other loads on the same circuit that could generate
electrical noise.
4A. High Idle Speed Mode Controls
Determine the combination of fast idle speed modes you will need (up to three xed
preset speeds and/or an optional variable RPM control). If you need the optional
variable RPM Control, you will need a 10k Ohm potentiometer (VRPM). For each
desired RPM1, RPM2, and RPM3 setting, you need one switch or relay contact to select
them. You will also need to implement a Fast Idle On/Off switch.
Wire these devices as shown in the Wiring Diagram for your respective engine: Diesel
(page 6-8) or Gas (page 9-16). Make sure to have a good quality chassis ground and a
+12 volt fused supply fed from the Ignition Switch. Refer to the most current applicable
Ford Body Builders Bulletin for location of these circuits.
Note on Variable RPM control: We recommend a three or up to a ten turn 10K
potentiometer such as those available from Digikey (www.digikey.com).
4B. Ford SEIC Wiring
Install the wires between the ETM51 module and the Ford SEIC as shown in the wiring
diagrams. On most F-250 to 550 trucks from 2005 to 2016, the SEIC wires are located
above the parking break pedal, and in the case of 2017 and after, they are located on
the Passenger Side. On F650 and F750 chassis, they are located under the hood on the
passenger side. Refer to the Ford SEIC documentation for more details.
WARNING: Please refer to most current Ford Body Builder’s Bulletin for applicable
year wire colors for your vehicle.

ETM51 Owner’s Manual
Setup and Calibration
The only calibration required is to select each of the three preset modes (RPM1,
RPM2 and RPM3) and adjust the three respective ten turn potentiometers on the
ETM51 to the desired RPM. This will be 900 to 2250 RPM on gas engines and
1200 to 2300 RPM on the 2005-10 diesel engines, and 900 to 3000 RPM on the
2011+ diesel engines. Each complete turn of the potentiometer will increase or
decrease the idle speed by roughly 300 RPM. Adjustments may be made with a
1/16ʺ (1.6mm) or smaller atblade screwdriver.
