Wiring Harness (Cont.)
1. The harness is very simple to understand and connect.
2. Lay the cords out on a floor and simply connect the same color connector to the same
color connector, (grey to grey) of the same type connector.
a. If two similar connectors have a similar color, match label.
3. Attach battery power as follows: BLACK ring to negative and RED to Positive terminals
of the battery. (2003-07 trucks have a second ground cable to battery negative)
4. Attach the Ignition/ACC wire to your accessories power, to an ignition controlled wire, so
control turns on and off with ignition switch (usually in your fuse panel).
a. Definition: ACC wire = Accessory Power Wire
5. Pull the exhaust brake toggle switch (for exhaust brake) and USB cables into the cab,
through the firewall.
a. 2007.5-2018 Cummins pull wire labeled PIN 20 into the cab as well.
6. Plug in the sensor wires as follows:
a. PURPLE END=Boost Sensor
b. GREY or YELLOW END=Exhaust Sensor
7. Plug actuator wire to the turbo actuator. It’s the only wire which fits the actuator. (DO
NOT BUMP OR BEND THE ACTUATOR, MISALIGNMENT CAN OCCUR).
8. Note: DO NOT LOOSEN OR ADJUST THE ACTUATOR FROM THE HOUSING. It is
calibrated to the housing it comes on. If you to need to reconfigure the actuator please
watch our CALIBRATION video in the instructions section of our website. If Diesel
Power Source, mounted the actuator you should not need to calibrate. But,
CALIBRATION IS ABSOLUTELY NECESSARY if the actuator bolts are ever loosened.
9. Download software from our Website https://www.dieselpowersource.com/installation-
instructions# (choose “DPS Turbonator® Software) which can tune and control the
actuator, but the control is pre-programmed for your vehicle from DPS, and is not
required to connect to a computer to operate properly.
a. Install BOTH the DRIVER and the APPLICATION files. Install both files.
Note 1: If you need to adjust the length of the harness connections must be soldered.
Note 2: If any part of the harness is shortened, which is not recommended. The wires must be
soldered, and heat shrunk.
Caution 1: Take caution when cutting the harness. There may be 2 or more wires side by side
with the same color code with different functions. Cutting harness could void warranty.
Caution 2: Only cut one branch at a time, once that branch is completed then move to another.
Cutting more than one branch may cause issues identifying how the branches connected.
