12-Circuit Mini-Fuse Universal Hot Rod Wiring Harness & Acc.

Wiring Harness

Our universal wiring harness is the perfect solution for vehicles with no reproduction harness options, custom builds, or the budget-minded DIY builder. This compact hot rod wiring harness works with nearly any 12-volt vehicle, engine, and transmission combination (carb or EFI, automatic or manual), including engine swaps. This 12-circuit wiring harness is ideal for basic vehicles with minimal power accessories.

A compact fuse box mounts discreetly out of view, or choose an open installation for easy access. Harness consists of 4 branches that are strategically bundled to simplify installation. The 12-foot-long tail light leads allow easy mounting in most compact and mid-size vehicles.

Plug-and-Play with GM Tilt Columns

Wiring up the steering column controls can be a daunting task, but our harness makes it easy. This harness plugs directly into most GM-style tilt steering columns. It connects to aftermarket tilt columns from ididit, Flaming River or Speedway Motors, as well as factory GM tilt columns from 1968-1996 cars, trucks and vans (see our full list of compatible GM columns). If you're sourcing a column from the junkyard, look for one with a flat "ribbon"plug, either 3-7/8"or 4-1/4"long (with 10 or more wires). Ignition switch plugs to connect "keyed"GM columns are also included in this kit.

Not using a GM tilt column? No problem. This harness easily splices into other steering columns with the included pin-out wiring diagram (it helps to have a wiring schematic for your vehicle here, too). Wires are conveniently bundled and labeled every 6 inches - just take your time and be attentive when splicing it in.

Modern High-Quality Insulated Wire

Patches and splicing are tedious and unreliable. Your car deserves better! Start fresh with modern polyethylene-insulated, stranded bare copper wire. Each harness is constructed from premium quality GXL automotive wiring, with the appropriate wire diameter for each fused circuit (ranging 8 to 16 gauge). Every strand of this wire harness is covered with a high-temperature (-40°F to +257°F) outer coating, color coded, and labeled to aid in a smooth installation for any DIY enthusiast. In other words, you can expect the same quality of automotive wiring used by the big 3 OE manufacturers.

Modular Design with Modern Fuses

An innovative 2-piece fuse block design gives easy service, fuse replacement, and endless mounting solutions. Mount the baseplate and then clip in the fuse block assembly. The clip-in fuse block detaches easily for service and arrives complete with modern ATO/ATC blade fuses and a common 2-prong style flasher. No more fragile, corroded glass fuses! Crimp connectors and terminals are included to get you started right away.

Conveniently Bundled Wires

Our universal 12-circuit harness consists of 4 branches that are conveniently bundled, so you can get started right away. Here's a quick rundown of those branches:

• Front of vehicle/engine feed wires (EFI engines will need an additional engine-specific harness)
• Dash panel instrument feed wires (mechanical or electric gauges)
• Ignition/lighting feed wires
• Rear of vehicle feed wires

The included 5-page instruction booklet, with color printed pictures, covers each of these pre-bundled circuits in detail.
