This universal kit is great for hot rod or street rod builds, but you'll find that it's easily adaptable to almost any vehicle and has enough length to handle full size and muscle cars. This harness comes with open ended ignition switch wires that can easily be adapted to any ignition switch out there. For those using a GM Keyed Column, Painless part number 10101 comes with a Pre-Terminated GM ignition switch connector. Included with this harness are the following parts: GM engineered fuse block & Painless mounting bracket, GM turn signal connectors, pre wired plugs for the headlights & dimmer switch. Each wire is printed with the circuit identification as well as using GM color codes for easy installation. Wire your classic car once and wire it right with a Painless Customizable wiring harness. Review: Great quality - The price is higher but after working with cheaper harnesses, painless is by far superior. The instructions are well written, the marking on all wires are present and legible. The wire break up is good for different sections of the vehicle. The fuse block is well built. Color matching is good for GM,but easy to convert to Ford. Not sure on functional yet as this is still a work in progress. The cheaper harnesses have missing or unreadable printing on the wires. The biggest problem with cheaper harnesses is the fuse block is poorly built. It is worth the extra cash to get quality and built in the USA. Review: Very easy to use and amd understand even for dummies. - I decided to build my first real drift car. Not just some coil and wheel type build. At first I was gonna redo the entire body harness from the car but after looking at the rats nest of wiring and shit I had no idea did what I decided to redo it all (with barely any wiring exp outside of some small projects). After looking at a few youtube videos (superfastmatt was a good one) I decided for me a universal harness would be good. I did not expect the kit to be this good. After wiring 80% of everything I need I can confidently say the wiring will work as I need it to without excess connectors or much wasted anything. I did get all the connectors and switches I wanted but with desertcart I am sure that wont be hard for others. Painless even has wiring diagrams for all the types of switches you could want. And then a wire explanation if just in case there is a type of switch you want to use but they don’t have a pinout for. All in all if you are new to this and wiring up a race car or non American project car. This is a great kit. Id recommend the bigger circuit one of you want power windows and locks but since I already wired those I went with with this kit. And glad I did. ## Features - Printed Wiring and Full Color Installation Manual: Every wire is printed with the circuit identification and uses GM color codes for easy installation; Paired with the highly detailed full color installation manual, Painless makes a tedious task simple.Fit Type: Universal Fit - Upgraded ATO bladed fuses: Leave antiquated glass fuses in the past where they belong and update to modern bladed fuses - Machine Crimped Fuse Block: Painless uses OE style machine crimping and pre-terminates the fuse block, leaving the installer with only one end to terminate - American Made, American Proud Since 1990: Every Painless harness is proudly produced in Fort Worth, TX, where we also staff our unmatched Technical Support department.; Need help during installsimply give us a call ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0006B3UF0 | | Best Sellers Rank | #334,030 in Automotive ( See Top 100 in Automotive ) #1,700 in Automotive Replacement Electrical Wiring Harnesses | | Brand | Painless | | Customer Reviews | 4.6 4.6 out of 5 stars (232) | | Date First Available | February 13, 2005 | | Is Discontinued By Manufacturer | No | | Item Weight | 7.54 pounds | | Item model number | 10102 | | Manufacturer | Painless Performance Products, LLC | | Manufacturer Part Number | 10102 | | Model | 10102 | | OEM Part Number | 10102 | | Position | Center | ## Images ![Painless Performance 10102 Classic Customizable Chassis Harness, Key in Dash, 21 Circuits - Image 1](https://m.media-amazon.com/images/I/81W2unxxvWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality *by T***N on November 7, 2025* The price is higher but after working with cheaper harnesses, painless is by far superior.

And glad I did. ### ⭐⭐⭐⭐⭐ Great instructions! *by A***R on December 2, 2024* Well thought out. Everything is labeled every 6”, color coded . Prewired to fuse block, only one end to hook up. Split up into three groups. Under hood, interior and rear of car, all wire tied in groups. Plenty of wire and detailed instructions. My only complaint is you have to buy the headlight and ignition switch, which they sell in a separate kit. Still a pretty good deal and a great time saver. --- ## 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.tn/products/15819723-painless-performance-10102-classic-customizable-chassis-harness-key-in-dash](https://www.desertcart.tn/products/15819723-painless-performance-10102-classic-customizable-chassis-harness-key-in-dash) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-08*
