Good To Know

Q: Does this harness retain steering wheel controls? A: This harness provides the necessary connections for audio signals and power, but steering wheel control retention typically requires an additional data interface module. Confirm your vehicle's specific needs before purchase.

Q: Is this T-harness compatible with all aftermarket radios? A: The harness uses standard aftermarket radio wire colors and connectors, making it broadly compatible with most single-DIN and double-DIN aftermarket receivers. Always match the wire functions from the radio's manual to the harness wires.
