Description
PAC LPHCH21 — 22-Pin Chrysler / Dodge / Jeep / RAM LocPRO Advanced T-Harness
CH21 is for the supported older Chrysler-family non-amplified radio architecture using PAC’s 22-pin connection. It gives a LOC, DSP or high-level-input amplifier clean access to the factory speaker signal and speaker wiring without cutting the original radio harness.
The important comparison is CH21 versus CH41 and CH42. They are different radio generations, not newer versions that can be swapped around. If the vehicle uses the later 52-pin or Uconnect 5 connection, this is the wrong harness even if the model name overlaps.
PAC’s labeled pigtails separate the power, front, rear and simple subwoofer-integration connections, and LPHEXT17 can add reach when the equipment needs to mount farther away. The signal conversion or tuning still comes from the LOC, DSP or amplifier connected to the harness.
PAC commonly lists CH21 across selected 2007–2020-era applications. Confirm exact model, factory radio connector and non-amplified audio package before ordering.
Harness only. LOC, DSP and amplifier are sold separately.

Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
Plan aroundVerify the source signal and vehicle architecture first.
Match itPlan inputs, outputs, summing, routing and gain structure as one signal path.
Finish itTune after installation, polarity, crossover capability and levels are correct.
