FAQ

Car wiring accessories help organize, connect, extend and protect electrical wiring in vehicles. Common options include wire connectors, terminals, fuse holders, wiring harnesses, cable ties and wire loom.

Car wiring accessories include crimp connectors, butt connectors, ring terminals, spade terminals, inline fuse holders, relay sockets, wiring harnesses, cable clips and split wire conduit.

Wiring harnesses group related wires and provide organized connections for components such as stereos, speakers, lighting systems and other vehicle electronics.

Wire connectors join wires or connect them to electrical components. Depending on the application, you can choose from butt connectors, quick-disconnect terminals, crimp caps, ring terminals and other connector styles.

Use cable ties, wire clips, conduit and wire loom to bundle cables, route them neatly and reduce clutter around vehicle electronics. Labeling wires and grouping them by function can also make future upgrades easier.
