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)?
The generic term is bullet connector. That's the male side, so you'll need a matching female connector. Did the head unit come with a bag of hardware or anything?
Thanks, solved. I didn't see any loose connectors in the bag. There are generally a lot of dead end wires with caps and various labels.
