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)?
Please don’t do wiring in a car if you need to ask questions like this. At least get your work looked at by someone who knows his shit.
It’s easy to make mistakes that can set your car on fire.
