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)?
Yeah, well maybe your first steps with electronics shouldn’t be with car wiring?
If he asked how to wire a three phase induction cooktop not knowing absolutely anything should I encourage him to electrocute himself?
Big difference between a major household appliance and a car stereo, when it comes to safety and consequences of wiring things wrong. For the cooktop, the worst that could happen is killing yourself. For a car stereo, generally the worst that could happen is frying the car stereo, supposing that it isn’t fused and doesn’t have circuits to protect against reverse polarity or other faults.
In fact, a car stereo is a pretty excellent and safe place to start learning electrical and really where many have gotten their start.
Ive seen many cars where somebody found their place to start working with electronics. Cables twisted together and held by electrical tape, positive connections spliced to anything that measures 12V including straight to the positive battery terminal. Wires crimped by screws or other components screwed over them. Now every time I see a car burned down to the ground I know what happened.
Im not against learning on your own equipment, but maybe watch a couple youtube videos first or read some manuals online. If op doesn’t know what a bullet connector is and where it goes it means they are flying blind with possibly no understanding of a basic safety regime when working with electricity where everything that works is already good enough.
