    Applications: For almost any car or truck with a front-mounted engine and the fuse block under the dash near the steering column. The harness works with the ignition switch mounted on the dash or steering column.

    To simplify installation, all the wires of this updated harness are attached to the fuse block. The "kit" features 20 circuits with 16 fuses in a small fuse block (requires only limited space under the dash). The horn relay, turn signal, and hazard flashers are mounted on the fuse block. All terminals are soldered using premium high-temperature wire for reliability, and the color-coded wires are labeled for easy identification.

    This wiring harness kit also has optional connectors for common GM-style accessories, such as dimmer switch, hazards, and alternator. For vehicles that don't use GM accessories, simply omit the extra connectors during installation. The wiring instructions show how to make all connections for GM, Ford, and Chrysler vehicles.

    10405 - JEGS Universal 20-Circuit Wiring Harness is rated 4.3 out of 5 by 16.
    Rated 2 out of 5 by from JEGS Performance Products 10405 Universal 20-Ckt I am building a hotrod and needed a wiring harness and fuse block for the job. I ordered the Jegs #10405 based on the picture and price. The package is well thought out and comes with instructions to make the job easier. There is one big issue though - the fuse block parts are low quality and do not interlock firmly. There are only 2 3/4" spacers to mount it. Add to that the flasher mount is screwed to the fuse blocks with one screw and looks like it will fall off.

    Rated 4 out of 5 by from Good quality wiring harness for it being universal. Love how the wires are organized. Wish there was a bracket that came with it for the fuse box

    Rated 3 out of 5 by from Great layout but... Bought a month ago. Wish it wasnt shipped with everything for a GM vehicle. Very vague instructions. Do not buy if you dont have ANY electrical experience. Plan on serveral calls to tech support.

    Rated 5 out of 5 by from Excellent harness with all the necessities. I bought this to replace an old scabbed together wiring harness in a kit car. Everything was bundled and labeled well. Guage of wiring was correct and adequate for needs of each circuit. The only potential draw back is that the fuse block does not have a mounting stand off to keep space beneath for the wiring so you have to utilize something else to give you spacing.

    Rated 2 out of 5 by from Great buy, they need better fuse assembly Very cheap and flimsy fuse holder, no cover for fuses, and could use more legth on all bundles that go to dash. It Used Quality labeled wire and very easy to identify what connects to where so Good for the price would recommend for budget builds . But will be sticking with painless or kwik wire for now on.

    Rated 3 out of 5 by from A fairly good start I have not installed the harness yet, but from reading the instructions there seems to be a lot of wire to buy yet, especially in circuits were several switches or relays need to be involved. If this is not true, Jegs should have included a tip or process method to help the customer.

    Rated 5 out of 5 by from A "Must-Buy" This harness was well laid-out with each and every wire clearly labeled on the insulation, making installation a breeze. Save yourself a ton of time and buy this. You'd have about the same or more invested in purchasing the components separately. Trust me.
