Review on 🔊 Aramox Steering Wheel Button: Versatile Metal + ABS Control Switch for iOS/Android - Enhance Radio, Volume, GPS and Bluetooth by James Yarbrough

If you connect this to an ATOTO S8 Gen2 Single Din as button 1 on one cable and button 2 on the other cable IT WILL NOT WORK! You need to connect (tie) the wires from Key One (1) and Key Two (2) together. Then it just works. I used a JST connector on mine and connected the two wires together on the connector. I'm not a big fan of twisting and then tying the wires together, but however you do it, just make sure you connect Key 1 and Key 2 together on the ATOTO HarnessRf TN Wiring Harness.
