WZruibo Wiring Harness 14-Circuit Universal — 9 ft Leads, Fuse Block & Removable Relays

WZruibo Wiring Harness 14 Circuit Universal is a complete, color-coded electrical kit designed to supply power and organized circuits for street rods, hot rods, rat rods, sand cars and classic car builds.

If you're rewiring a custom vehicle or replacing an aging loom, this 14-circuit universal harness delivers labeled fusing, an extra-long main lead, and modular relay/flasher components to simplify installation. It combines a full fuse block with add-on fuse positions, a heavy diode circuit for MSD-style ignition protection, and removable 40A relay and flasher modules so you can adapt the harness to a wide range of restorations and custom projects.

What does the kit include and how is it organized?

The kit arrives as a single 14-circuit harness with plainly marked wires and a protective cover over the fuse legend. Each main circuit is nine feet long, giving generous reach through most engine bays and passenger compartments, and the harness includes a horn/AC 40 amp relay and a removable flasher module.

• 1 × 14-circuit harness with fuse block and cover
• 14 fuses with extra add-on positions and detailed wiring legend
• Removable 40A horn/AC relay and removable flasher module
• Color-coded wires and documented pages for GM, Ford, and Mopar routing

How does the harness handle ignition or MSD-style devices?

This harness includes a heavy diode protection path designed to prevent interference or unintended operation with MSD and similar ignition devices. The diode isolates sensitive ignition circuits while keeping the rest of the system fused and protected.

• Dedicated diode-protected ignition circuit
• Fused inputs reduce risk of overload to auxiliary systems
• Clear labeling helps installers route ignition and starter wiring correctly

What are the physical dimensions and installation considerations?

Key mounting and size measurements are included so you can plan a clean fit: the flasher height, mounting distances, and overall widths are specified, and wire lengths are intentionally long to accommodate routing in many chassis types. While the harness is made for DIY-minded builders, professional installation is strongly advised for safety and reliability.

• Flasher height from base: 7.62 cm
• Mounting point edge-to-edge: 12.70 cm; flasher to relay width: 11.49 cm
• Each main circuit wire length: 9 ft (approx. 2.74 m)
• Extra-long wires for flexible routing; professional installation recommended

Which vehicles and builders is this harness best suited for?

The WZruibo 14-circuit harness was designed with custom and classic vehicle builders in mind. It's appropriate for street rods, hot rods, rat rods, sand cars and many classic car restorations that need a straightforward, labeled electrical foundation.

• Commonly used in street rods, hot rods, rat rods and sand cars
• Good fit for complete rewires or upgrades from aging looms
• Includes GM, Ford and Mopar-specific wiring pages to guide routing

WZruibo includes a 12-month warranty to protect your purchase and give you peace of mind. The harness combines modular components and color-coded wiring with clear documentation, making it a practical choice for builders who want a tidy, serviceable electrical backbone without designing a loom from scratch.

Who is this for: builders and mechanics restoring or customizing classic vehicles who want a comprehensive, labeled harness with generous wire lengths, removable relay and flasher modules, and diode protection for ignition devices. If you prefer a plug-and-play aesthetic but plan to rely on proper system grounding and routing, this harness provides the structure you need—however, we strongly recommend professional installation for safety and to ensure every circuit is connected correctly.
