Good To Know
Q: Does this harness include a wiring adapter for steering wheel controls? A: This T-harness focuses on integrating the radio and data signals, so steering wheel control modules are typically handled separately. Confirm your vehicle's specific options when planning the install.
Q: Will this work for a base model without factory amplified audio? A: The LPHGM71 is built for standard factory audio systems, but the specific trim level can affect compatibility. It is best to verify your vehicle's radio and chime features.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
