Review: Great Amp Bypass Harness- 2004 IS300 - Great Bypass Harness, 2004 Lexus IS300. Lots of extra wire. Some leads were unused. Lots of install tips/hints around the web, but always miss some technical details. There are many ways to go about this install. Verify all connections before powering the system. Double din Pioneer touch using the built-in amp. No subwoofer. Removed the factory amp. Installed aftermarket rear 6x9 speakers (will need brackets), using the factory rear connectors. PSA- Solder and heat-shrink or crimp connectors. Don't burn your car down with poor wiring. Do NOT use the factory Toyota rear speakers- You can/will fry your Head Unit internal amp. *Metra Bypass Harness* 1. Radio connector- did not use the blue wire. Straight forward. 2. Amp connector- Striped yellow, striped brown, striped green, stripped red wires unused. I used the factory rear connectors (The striped wires that went to the woofer section). This means the METRA harness needed the Rear Right Leads (PURPLES) re-pinned to where the yellow and brown wires were. Sounds Excellent, everything works. Review: Worked great in a 2002 Camry LE - Thankfully, this allowed us to bypass the weak JBL amp that's installed at the factory. Any new stereo/radio will NOT work unless this factory amp is by-passed. In the 02 Camry the factory amp is tucked in the footwell panel underneath the glove compartment. Simply: (1) unplugged the old amp (2) plug this matching harness in it's place, (3) trim the really lengthy wiring provided as needed (4) then attach to your color-coded new radio harness! Voila! you have a much better stereo/radio than the stock unit-- a pain to circumvent the factory amp, but this harness did the trick! ## Features - VEHICLE COMPATIBILITY: Designed specifically for Toyota vehicles manufactured between 2000-2009, this amp bypass harness enables aftermarket radio installation by bypassing the factory amplifier system. - PLUG-AND-PLAY INSTALLATION: Direct replacement harness eliminates the need for cutting or splicing factory wires, preserving your vehicle's original wiring integrity and simplifying the installation process. - PREMIUM CONSTRUCTION: Features high-quality wire construction and durable connectors that ensure reliable signal transmission and long-lasting performance in automotive environments. - COMPACT DIMENSIONS: Measures 2 inches in length and 7 inches in width with a height of 14.5 inches, designed to fit seamlessly within your vehicle's dashboard space without interference. - MANUFACTURER PART NUMBER: Metra part number 70-8116 ensures accurate fitment and compatibility verification for your specific Toyota model and year range. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007WQ92O | | Best Sellers Rank | #274 in Car Audio & Video Wiring Harnesses | | Brand Name | Metra | | Cable Type | Flat Ribbon | | Connector Type | Aftermarket Radio Connector, Oem Connector | | Customer Reviews | 4.2 4.2 out of 5 stars (196) | | Global Trade Identification Number | 00086429115280 | | Included Components | Wire Harness^Manual | | Item Dimensions | 14.5 x 7 x 3 inches | | Item Type Name | Audio | | Item Weight | 0.1 Pounds | | Manufacturer | Metra Electronics Corp | | Material Type | Copper Wire, Plastic Connectors, Pvc Insulation | | Model | 70-8116 | | Part Number | 70-8116 | | UPC | 086429115280 | | Unit Count | 1.00 Count | | Warranty Description | 1 Year Limited | | Wire Diameter | 1.29 Millimeters | ## Product Details - **Brand:** Metra - **Connector Type:** Aftermarket Radio Connector, Oem Connector - **Item Weight:** 0.1 Pounds - **Item dimensions L x W x H:** 14.5 x 7 x 3 inches - **Material:** Copper Wire, Plastic Connectors, Pvc Insulation ## Images ![Metra Electronics Metra 70-8116 Factory Amplifier Bypass Harness for Select 2000-2004 Toyota Vehicles with Amplified JBL System - Image 1](https://m.media-amazon.com/images/I/61lAZu3wFoL.jpg) ## Available Options This product comes in different **Customer Package Type, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Amp Bypass Harness- 2004 IS300 *by T***T on October 12, 2020* Great Bypass Harness, 2004 Lexus IS300.

I used this to bypass the factory amplifier on my 2006 Toyota Higlander Hybrid Limited with the factory JBL system. This kit comes with all the attachments and plenty of wire, and even comes with a radio adapter harness, although I didn't use it nor do I recommend you use that part. It's simply not needed, and is missing key connections like antenna wires and illumination wires. It's basically just 12V, switched, ground and remote. The instructions suck. There's practically none, so i would recommend leaving this to the pros unless you understand how to read factory wiring diagrams and have a background in audio to avoid digging yourself a hole. I found more comprehensive instructions off of metra's website, but the fact I had to go looking for it felt a little sloppy on metra's end. Now if Amazon could actually send me the correct amp so I can put a 5-channel amplifier in there and run some subs... --- ## 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.us/products/16233445-metra-electronics-metra-70-8116-factory-amplifier-bypass-harness-select](https://www.desertcart.us/products/16233445-metra-electronics-metra-70-8116-factory-amplifier-bypass-harness-select) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
