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: Wow just wow! - Just got and have not installed yet, but I would say definitely worth the extra money in this one!! Instructions are amazing, wires are marked and get this…you can read them without a magnifying glass and prayer! Ok should have bought this originally! Now keep in mind I know the basics so I would say this is great for those who know enough to be dangerous. If you are well versed in wiring you may want to go a different route. I love that it is made in the USA and they have an actual support number …mind blown! ## 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 | #385,015 in Automotive ( See Top 100 in Automotive ) #2,007 in Automotive Replacement Electrical Wiring Harnesses | | Brand | Painless | | Customer Reviews | 4.7 4.7 out of 5 stars (239) | | Date First Available | February 13, 2005 | | 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. 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. ### ⭐⭐⭐⭐⭐ Wow just wow! *by K***E on November 3, 2023* Just got and have not installed yet, but I would say definitely worth the extra money in this one!! Instructions are amazing, wires are marked and get this…you can read them without a magnifying glass and prayer! Ok should have bought this originally! Now keep in mind I know the basics so I would say this is great for those who know enough to be dangerous. If you are well versed in wiring you may want to go a different route. I love that it is made in the USA and they have an actual support number …mind blown! ### ⭐⭐⭐⭐⭐ So happy that I bought Painless. *by B***Z on December 17, 2020* I spent a LOT of money on many spools of multiple gauges of GXL wire, connectors, etc. Thinking I'd just do it all myself. After buying all that and speaking to a buddy who's looking into a re-wire of his vehicle, I opted to get a Painless harness. Man, am I glad I did. The Painless manual itself is worth money. Things I didn't even consider are covered, plus basically having it already wired up to the fuse block, separated into branches, color coded and PRINTED wire identifiers. Awesome. I'm two months into my re-wire job (little bit here, little bit there, it's cold out!). Slow going is no fault of Painless -- that's just me in no hurry and moving slow. I am now finally nearing the end, can't wait to hook up the batteries and see sparks fl... see everything work flawlessly! --- ## 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.at/products/15819723-painless-performance-10102-classic-customizable-chassis-harness-key-in-dash](https://www.desertcart.at/products/15819723-painless-performance-10102-classic-customizable-chassis-harness-key-in-dash) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-12*
