Axxess AXTO-CH2 Data Interface car electronics accessory 12-volt 10-amp

SKU CH-M4JT-R2XG3

Data interface for select 2002-2008 Chrysler and Dodge vehicles retains accessory power and provides NAV outputs with adjustable gain control

  • TypeWire Harness
  • Delivers 12-volt 10-amp accessory power for aftermarket gear
  • Keeps retained accessory power active after key removal
  • Supplies NAV outputs for parking brake, reverse and speed sense
  • Pre-wired for AXSWC steering-wheel control integration (module sold separately)
  • Adjustable gain control balances overall volume with high-level speaker input

Vehicle Compatibility

The Axxess AXTO-CH2 data interface is built for select Chrysler and Dodge vehicles produced between 2002 and 2008. Supported models include the Dodge Ram 1500 from 2002 to 2004, Ram 2500 and 3500 from 2003 to 2004, and the Chrysler Pacifica from 2004 to 2008. It supplies a 12-volt 10-amp accessory power feed and retains the factory retained accessory power feature.

Factory Amplifier Upgrade

This wire harness replaces the original radio connection in vehicles equipped with amplified audio systems. It provides high-level speaker inputs and an adjustable gain control so the new head unit can drive the factory amplifier cleanly. The interface also preserves balance and fade controls while adding navigation outputs for parking brake, reverse and speed sense signals.

Installation Requirements

Verify that your vehicle matches the listed model years before ordering, as the harness is not universal across all Chrysler or Dodge platforms. The pre-wired AXSWC harness supports steering wheel control adapters, but the AXSWC module itself is sold separately. A Micro-B USB port allows firmware updates if future revisions become available.

Questions about this item

What connectors does the AXTO-CH2 need to plug into the factory wiring of a 2003 Ram 2500?

The interface uses a pre-wired AXSWC harness that connects to the vehicle's factory plug; the AXSWC steering-wheel control module is sold separately.

Which step do installers most often miss when fitting this interface in a 2004 Chrysler Pacifica?

After wiring the high-level speaker inputs and NAV outputs, the adjustable gain control must be set so the aftermarket radio's volume matches the factory amplifier level.

What part of the AXTO-CH2 will need attention if the retained accessory power stops working years later?

The 12-volt 10-amp accessory power circuit inside the interface; if R.A.P. fails, the unit itself would need replacement.
