I’m installing a stereo head unit and don’t have sound. This blue wire comes from the included harness and is the amp control wire. The control wire on the other connector at the unit also says amp control and isn’t connected to anything. I’m assuming I have to connect the two wires and this thing (plus heat shrink wrap…?) will help. I’m unsure if I should use this or cut and strip the wires and find some wire nuts. How do I use this connector, (if it even is one)?

    Male end bullet connector specifically. And blue wires in stereos are generally the remote on switch signal line. When you turn on your radio this tells any antennas or amplifiers to turn on and off when you turn off the radio or car.

      Thanks, solved. That’s why I’m thinking this is important to connect, although I’m not sure why it wouldn’t have a female connector on it. All of the reading I’ve done said the amp power was the issue. Sure enough when I started following the wires, the amp control isn’t connected. Blue has several labels on this unit, also bring the Bluetooth antenna wire.

        Most aftermarket installations just use a splice connector on the 12V that runs to the cigarette lighter.
