    SKU-91010309
    x
                

    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 i
