Car Terminals & Connectors

Car Electronics Connectors and Terminals

When it comes to automotive electronics such as lighting, alarm systems, audio equipment, etc., there are always lots of wires involved. Loose cords and gobs of electrical tape can be messy and confusing. Luckily, there are tons of wire connectors and terminals available to make managing them easier, more efficient, and more organized.

What systems do you need connectors or terminals for?

Here are some examples of systems with lots of wiring that can benefit from connectors:

  • Alarm system: An alarm system has leads on it that go to the power, the horn, the door latches, and the lights on your vehicle.
  • Audio system: Depending on how complex your audio system is, there could be dozens of different leads and cables to connect and keep track of between different equipment, such as the receiver, speakers, tweeters, the subwoofer, and the amplifier.
  • Lighting: Lighting systems have leads running between the lights themselves, the battery, and the mechanism used to turn the lights on and off.
  • Remote start: A remote start system has to be tied into the ignition of the vehicle, the battery, and the receiver for the unit.
What types of terminals or connectors are available?

Here is a small sample of the connectors and terminals available to suit your needs and make the job easier:

  • Screw terminals: Screw terminals can be installed just about anywhere. They are commonly used on amplifier or subwoofer boxes. The terminals can be installed on the box or other stationary surface and the leads then wrap around the screw, which is then tightened down to hold them securely in place and keep them in contact with each other and nothing else.
  • Pins and pin terminals: A pin is basically a short, skinny metal tube that you insert the end of a lead into. You then use pliers or a crimping tool to crimp the tube onto it. The metal tube then conducts the signal from the lead and can be inserted into a pin terminal. The terminal has a latch on it, which you can push down after inserting the wire into the terminal to clamp onto the pin to connect the wire.
  • Butt connectors: Butt connectors, as funny as the name sounds, are quite simple. A metal tube is encased in a soft plastic or silicone. You insert a wire into each end to join them, and then use pliers or a crimp tool to crimp the tube and hold the wires securely inside.
  • Wiring harnesses: You can find harnesses that will greatly diminish the amount of connectors youll need to install your electronics. These harnesses have terminals on each side to attach the wires to. You can then disconnect and reconnect the two halves as needed to make adjustments.
  • Connector kits: There are a multitude of kits on the market that contain a wide variety of different sizes and types of wire connectors. This way youll always have options for all of your wire needs.
