LIMICAR 5-Way Trailer Wire 100FT 18 Gauge Bonded Spool, Color-Coded SAE-Rated for Lights & Brakes

The LIMICAR 100FT 18 Gauge Bonded 5-Way Trailer Wire is a complete spool of color-coded, SAE-rated wiring designed to rewire trailer lighting and electric brakes with a tidy, single-run installation.

If you're rebuilding or upgrading trailer wiring, this 100-foot wishbone-style spool gives you five parallel conductors pre-bonded in a durable PVC jacket so you can run one neat cable instead of managing individual wires. Each conductor is color-coded to standard trailer functions and the assembly is suitable for boats, utility or landscape trailers, horse trailers, and more. The wire meets SAE J1128 expectations for automotive wiring, resists oil and acids, and is intended for 12V tow systems using five-pin connectors.

How does this spool simplify a full trailer rewiring?

Because the five conductors are bonded into a single flat cable, you pull and secure one assembly rather than separate wires, reducing installation time and snag points. The wishbone layout hugs a frame well and keeps routing tidy along crossmembers or inside conduit.

• One 100-foot length covers most full-size trailers with spare wire for spares.
• Color-coded conductors eliminate guesswork at connectors and grounds.
• Bonded design prevents tangles and speeds routing along frame rails.
• Flexible PVC jacket allows easier bends around corners and brackets.

What connectors and trailer types is it compatible with?

The LIMICAR 5-way bonded wire is built for standard 5-pin trailer plugs—both flat and round styles—and supports vehicles with 12V systems and brake controllers. It covers typical applications including open and enclosed cargo trailers, flatbeds, boat trailers, and horse or ATV trailers.

• Works with common 5-pin flat and round trailer connectors.
• Blue conductor dedicated for electric trailer brake signals.
• Designed for 12V tow vehicles including trucks, SUVs, and pickups.
• Suitable for marine and outdoor-exposed wiring with UV-resistant jacket.

Is this wiring robust enough for outdoor and marine use?

The cable uses oil- and acid-resistant PVC insulation rated to 60V and constructed to SAE J1128 standards, which gives it good resistance to elements typically encountered on trailers. While it is designed for continuous outdoor exposure, proper routing and protective clips or conduit in harsh environments will extend service life.

• PVC jacket resists UV, moisture, oil, and common road chemicals.
• 18 AWG conductors provide a balance of flexibility and current capacity for lighting and brakes.
• Bonded assembly reduces wear from rubbing or chafing on frame surfaces.
• Recommended to use grommets or conduit where wires pass through metal or bulkheads.

What tools and steps are needed for DIY installation?

Installation is straightforward: cut to needed lengths, separate the color-coded conductors where connections are required, and attach to lights, grounds, and the brake controller using crimp or solder joints. No specialized equipment is mandatory beyond common hand tools, making this suitable for experienced DIYers and professional installers alike.

• Cut the spool to length, split conductors at each connection point.
• Crimp or solder connections and protect with heat-shrink or quality connectors.
• Secure with clips or zip-ties every few feet to prevent movement.
• Verify function with a trailer light tester or multimeter before finalizing.

Who is this for: the LIMICAR 100FT 18 GA 5-way bonded trailer wire is ideal for DIYers and professional trailer shops who need a tidy, full-length solution for rewiring lighting and electric brakes on trailers of many kinds. It's aimed at users replacing worn harnesses or building new trailer wiring runs who want standardized color coding, a single-run cable for cleaner routing, and material rated for outdoor trailer use. If you require a longer or heavier-gauge run for unusual loads, consult an electrician or upgrade to a thicker wiring kit tailored to higher current needs.
