For example , headlights, turn signals, dome light, trunk light, wipers, lighter.... so forth? Thanks** A: Yes it comes with a small booklet that explains everything in detail. Further, each wire is also labeled like headlight+ or headlight -. It allows for wires to be added or taken away. Walks you thru step by step. It is still helpful to get the schematic and color coding for your vehicle as this is generic. It allows for major American makes. Your particular model may use a different size wire for some parts like sensors. The kit is size 14 but like some models sensors use 18 or 20. So do your homework and get a couple spools of wire for them. The biggest safety item is to disconnect the battery completely, negative and positive! If you get stuck send another question out to me. **Q: Are the wires copper core wires? or aluminum wire?** A: All wiring is copper. **Q: 2,3 ford long block motor** A: works great and ends are marked perfectly **Q: what is length of front and length of rear of wires extended from fuse box?** A: front is 6 foot back is about 10 ft ## Customer Reviews ### ⭐⭐⭐⭐ Sehr umfangreiches Kit *by B***Y on 9 February 2026* Das Kit als solches finde ich super.

Would order again. Great lengths for bigger cars. *by A***R on 17 April 2025* Lengths are good. Quality is good. Pliable wires with many stands inside the wiring. Flasher relays are cheapo's but this harness is 1/5 the cost of the big brand versions found online. If they fail I'll buy the expensive $10 relays. I have a 37 International D-2 ratrod. I have AC and electric windows so needed the expanded capabilities of the harness. If you've never wired a car and don't understand electrical schematics the directions might seem poor. If you can typically troubleshoot a car using a schematic the directions seem quite straight forward in my opinion. I'd order this one again vs the awfully expensive versions available which seem to come from the same continent but have better directions. The directions are not worth the extra several hundred bucks for my situation. 21 circuit might be overkill for a simple muscle car but you can always take wires out. Did buy extra crimp on connectors but it does come with terminations for lights. Gives you alternate wiring diagrams depending on the brand of your vehicle. simple and helpful. Also directions if you are running a single wire GM alternator. Basic stuff but nice they include it. ## Frequently Bought Together - JY PERFORMANCE Universal 21 Circuit Wiring Harness Kit Extra Long Wire Standard Color 17 Fuses for GM Chevy Mopar Hotrods Ford Chrysler - MGI SpeedWare 4-Position Universal Ignition Key Switch for 12V Car, Truck, Tractor, Trailer, Forklift - Acc/Off/IGN/(Start) - Standard Motor Products DS72T Dimmer Switch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/502746521-universal-21-circuit-wiring-harness-kit-extra-long-wire-standard](https://www.desertcart.fr/products/502746521-universal-21-circuit-wiring-harness-kit-extra-long-wire-standard) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-06*
