How to use

Turn off vehicle ignition and remove the factory radio according to the vehicle manufacturer's service instructions. Disconnect the factory radio connector and plug the corresponding side of the BLOW adapter harness into the vehicle loom. Connect the aftermarket radio's ISO connector to the harness. Ensure all connections are fully seated and secure the harness to prevent strain on wiring. Restore power and test radio functions including power, speaker output, accessory on/off, and illumination before reassembling the dashboard.

Usage recommendations

Check the vehicle wiring and the aftermarket radio's pinout before installation to confirm ISO compatibility. If the vehicle has additional steering wheel controls, CAN-bus interfaces, or amplified factory audio systems, separate adapters or interface modules may be required for full functionality. Use basic hand tools and avoid forceful connector insertion to prevent damage to pins or housings.
