Painless Wiring 10308 18 Circuit Modular Wiring Harness
SKU-91010308
                        

Designed for those with a T-Bucket or Roadster with minimized needs. This compact, streamlined, simple to install harness has all the basic circuitry needs: headlights, tail lights, brake lights, turn signals, hazards, horn, gauges, wipers, radio, electric fan, electric choke and one accessory circuit. Each wire is color-coded and printed the entire length for ease of installation. As an added plus, the fuse block is modular so if you decide at some point to add additional accessories to your bucket, you can easily snap another four circuits into place. Also included are connectors to GM/Ididit/Flaming River Columns for ignition switch and turn signals and a heavy-duty lead for a high-output alternator.

This wiring harness is just a nice simple basic harness that will work well in a variety of vehicles. It’s for “minimalist” vehicles with no power windows, no power door locks, no power seats... just the basics. Works well in any of the Speedway kit cars.

Painless Wiring 10130 14 Circuit Remote Mount Microfuse Wiring Harness
SKU-91010309
                        

This Painless Micro Fuse Harness solves a dilemma faced by many custom car builders: where to mount the fuse block.  With engine compartments becoming more crowded and underdash space at a premium, there often is not room for a standard size fuse block. The new Micro Fuse Harness is the answer.

The key element is the fuse block itself: it measures just 3" x 3-1/2" x 2" yet holds 12 fuses and 2 relays. You can easily tuck it up under the seat or, because of the unique design of this harness, mount it in the trunk. The fuse block is covered to keep it free from dirt and contaminants.

Wiring harness is designed with three major groups incorporated into it:

  • Engine/Headlight Group Includes: high beam, low beam, park, right turn, left turn, electric fan, horn, starter solenoid, battery feed, alternator (output/exciter wire), coil, water temperature, oil pressure and air conditioning.
  • Dash Group Includes: wires to connect gauges, indicator lights and switches to their proper sources.
  • Rear Light Group Includes: taillights, dome lights, left and right turn signals, brake lights and fuel sender.

The kit includes a 10 gauge alternator wire for use with high amperage (over 65 amps) alternators. All wires are color-coded and printed along their entire length for ease of installation. A comprehensive installation manual with charts and diagrams is included.
