16 Gauge Yellow TXL Wire 50ft

The 16 Gauge Yellow TXL Wire 50ft from Painless Wiring is a professional-grade primary conductor engineered for custom automotive electrical harnesses, restoration builds, and high-heat engine bay installations. Whether you're rewiring a classic muscle car, upgrading a modern performance platform, or building a race-spec standalone ignition system, this yellow-insulated TXL wire serves as a reliable backbone for auxiliary circuits—charging systems, fuel pumps, fans, and aftermarket accessory feeds. Mechanics and fabricators choose Painless Wiring for consistency, color-coding accuracy, and proven durability in demanding underhood environments where standard automotive wire fails.

TXL insulation is a cross-linked polyethylene compound that resists heat, oil, and abrasion far better than PVC alternatives—critical when routing near exhaust manifolds, turbochargers, or header tubes where ambient temperatures routinely exceed 180°F. The 16-gauge conductor diameter (approximately 1.3 mm) carries 13–16 amps continuously, making it ideal for moderate-draw accessories and sub-circuits within a larger harness architecture. Painless Wiring's yellow color-coding follows industry standard conventions, simplifying troubleshooting and future service work. The 50-foot spool length accommodates most full-frame restorations or modular engine bay projects without excessive splicing.

This wire is essential for restorers, hot rodders, and performance tuners who demand longevity and compliance with modern wiring standards. Use it for auxiliary lighting circuits, electric fuel pump feeds, fan relay outputs, and secondary ground distribution in race cars or restorations where OEM harnesses are removed. Pair multiple spool purchases to build complete custom looms, or integrate into Painless Wiring modular harness kits for seamless system expansion. Always verify amperage requirements for your specific load and terminate with proper crimped connectors and heat shrink for maximum reliability and safety.
