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 utilizing APM/ATM spec "mini" blade fuses 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 ). 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 APM/ATM spec "mini" 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.

Installation Tips
- Switches and relays are available individually:
- Kit has two flashers for turn and hazard and they are the 2 prong style
- 30 amp fuse for heat/cool
- Two 30 amp relays, one each for the horn and electric cooling fan
- Horn and electric fan both have 20 amp fuses in dedicated circuits
- Main harness is over 12’ in length to satisfy most applications
- Headlights are on a 30 amp fused circuit
- Installation Tip: The back of the fuse block un-snaps from the fuse block (see above photos). By releasing the back unit from the fuse block, the installer is able to then mount the back unit where required for installation purposes and then re-snap the fuse block assembly back into the base unit.

Trick piece Rated by Rtm on August 23, 2021
Summary: Don't panic if fuse box mount is missing. It's not sold separately anyway. Take fuse box apart, grind the two knobs off the bottom. Pop rivet into place, mindful of what's on the other side of wherever. On the end where wires come out, silicone a small piece of oil bottle. About a quarter size. And there ya go..
Yes, I recommend this product.
Drawbacks Rated by Jack on August 17, 2021
Summary: When trying to separate the fuse block from its mounting bracket the tabs holding it together broke off. Fuse block no longer stays in mounting bracket - zip tied it together. If not for that I would have given 5 stars.
No, I would not recommend this product.
I would buy again. Rated by Artie on June 11, 2021
Summary: This will go in my T-bucket. It could have had a better mount for the fuse block, however I made one and adapted it to the block to screw right into the car's inner firewall. The price on this kept shooting up, so ordered one before it was out of range.
Yes, I recommend this product.
