ANC-CH01
Rev: V3
Date: 071819
Introduction and Features
The ANC-CH01 harness bypasses the Active Noise Cancellation (ANC) module in select Chrysler, Dodge, Jeep and
RAM non-amplified audio systems while maintaining communication between the vehicle’s CAN bus network and the
module. Aftermarket amplifiers can easily be added with no need to cut or modify a vehicle’s original wiring.
Installation Notes
1.
WARNING: Passing the speaker signal from aftermarket amplifier through the ANC module will cause DAMAGE!
2.
The ANC-CH01 is only compatible with non-amplified vehicles that have the ANC system. To determine compatibility, some
key factors to look for would be the inclusion of an active center channel and / or subwoofer. If the audio system includes either
or both, the ANC-CH01 is not compatible because the system is factory amplified.
3.
The ANC-CH01 can be used to provide speaker wire connections for all 4 speakers, eliminating the need to cut into the factory
harness (see “Installation Steps” for info.).
4. When using the ANC-CH01 harness to connect speaker wire outputs from an aftermarket amplifier, it is always best to use a
tone generator (PAC part number TL-PTG2) to verify that the tables in this manual match the wiring in your specific vehicle.
1.
Locate the vehicle’s ANC module and disconnect the 16-pin and 22-pin connectors.
a.
RAM Truck:
The ANC module is under the driver’s seat
b.
Jeep Cherokee:
The ANC module is above the glove box
c.
Chrysler Pacifica:
The ANC module is to the right of the glove box
2. Connect the ANC-CH01 harness to the connectors that were
disconnected in the previous step.
3. Connect the male 22-pin connector from the ANC-CH01 to the ANC module.
4. When connecting the ANC-CH01 to the outputs of an aftermarket amplifier, use the wiring information (provided in the chart
below) to determine which will be used.
a.
Cut the wires in the ANC-CH01 that will be used for connection to the aftermarket amplifier speaker outputs. The
wiring overview (provided in the chart below) shows the approximate location of where the wires should be cut.
b.
Leave any speaker wires that are going to be powered from the radio (rather than from an aftermarket amplifier),
intact.
c.
Connect the outputs of the aftermarket amplifier to the appropriate wires in the ANC-CH01 harness that go to 16-pin
side of the cut harness.
d. Insulate the cut wires that lead to the 22-pin side of the harness as they will not be used.
