Connector Type
There are many different ways to connect wires together. Often times when doing your own installation, you will be in need of specific types of connectors. This is the specific type of connector or terminal that is included with this item.

Bullet and Butt connectors are used to connect to wires together. Butt connectors are often used when installing an aftermarket headunit to the factory harness.

Quick Disconnect Connectors are used primarily in head unit or speaker applications. They provide a simple and easy way to connect or disconnect your wire.

Quick Splice Adapters and T-Tap Connectors can quickly tap a wire to already connected wire.

Relays, Relay Sockets and Switches are used for electronic applications such as car alarm installations and other audio applications.

Ring and Spade Terminals connect wires to a terminal. These are mainly used in battery hook-up, amplifier connection, speaker connection, and other various installation applications.
Connection Gender
This is the gender of the connector. Usually a specific type of connector will have both male and female connectors.

Please make sure that you order the correct gender of connector that is required for your installation.
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Primary Color
This is the main color of the item.
