Review: worked great to swap a ls2 silver blade body onto an 8.1 engine - if you are looking to upgrade your stock poor flowing 99-02 8.1 throttle body this harness is what you need. plugs right into a 6,0 vette silver blade intake but you will need to swap the 2 pins on the actuator plug for throttle body to function. stock intake boot will fit but trimming the fan shroud and replacing factory intake is recommend for performance applications. long tube headers with good wires in addition to this throttle body upgrade has increased my mpgs and power so far without a tune. im planning on installing a raylar intake and cleaning up my head ports soon to hit my power numbers. sound increase with all this done on stock system is minimal Review: Works well - Looks like decent quality and it works well so what more can you ask for? ## Features - LS1 to LS2 Throttle Body Adapter Harness for Plug-and-Play Conversion – Easily adapts an LS2 drive-by-wire throttle body to an LS1 vehicle, eliminating the need for complex rewiring or modifications. - Compatible with LS1 Vehicles Including C5 Corvette & CTS-V – Designed to work seamlessly with 1997-2004 C5 Corvette, 2004 CTS-V, and other LS1-powered vehicles, making LS2 throttle body upgrades simple and hassle-free. - OEM-Quality Connectors for a Secure & Reliable Connection – Features factory-style connectors that ensure a tight, weatherproof fit, maintaining consistent throttle response and ECU communication. - Perfect for LS1 to LS2 Throttle Body Upgrades – Allows LS1 owners to upgrade to an LS2 throttle body, which offers improved airflow, better throttle control, and enhanced performance potential. - Plug-and-Play Installation – No Cutting or Splicing Required – This direct-fit adapter harness makes installation quick and effortless, allowing you to convert your throttle body in minutes with a factory-like connection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HHLFQ9N | | Best Sellers Rank | #311,003 in Automotive ( See Top 100 in Automotive ) #1,531 in Automotive Replacement Electrical Wiring Harnesses | | Brand Name | Michigan Motorsports | | Cable Type | Auxiliary | | Connector Type | Deutsch Dt, Spade | | Customer Reviews | 3.9 3.9 out of 5 stars (72) | | Included Components | (1) LS1 to LS2 Throttle Body Adapter Harness | | Item Weight | 0.06 Kilograms | | Manufacturer | Michigan Motorsports | | Material Type | Copper | | Model | B3300 | | Part Number | B3300 | ## Product Details - **Brand:** Michigan Motorsports - **Connector Type:** Deutsch Dt, Spade - **Item Weight:** 0.06 Kilograms - **Manufacturer:** Michigan Motorsports - **Material:** Copper ## Images ![LS1 to LS2 Throttle Body Adapter Harness - Plug-and-Play Drive-by-Wire Conversion for LS1 Vehicles - Fits C5 Corvette, CTS-V, and More - Image 1](https://m.media-amazon.com/images/I/61xQUaMg3RL.jpg) ## Questions & Answers **Q: Will this work on an 03 Silverado 4.8 gen 3** A: Yes, it works on both engines 5.3 and 4.8...same throttle body **Q: Does it fit a 1998 Lexus GS 300** A: No, this is a Chevy part. **Q: Will this let me use a drive by wire without an external tps on my 2002 corvette ls1, 5.7l?? what are the 3 plugs hook up to?** A: Yes, you just have to use the newer TB. **Q: Will this work 06 silverado harness to tbss tb?** A: It shouldn't need it ## Customer Reviews ### ⭐⭐⭐⭐⭐ worked great to swap a ls2 silver blade body onto an 8.1 engine *by D***B on July 19, 2023* if you are looking to upgrade your stock poor flowing 99-02 8.1 throttle body this harness is what you need. plugs right into a 6,0 vette silver blade intake but you will need to swap the 2 pins on the actuator plug for throttle body to function. stock intake boot will fit but trimming the fan shroud and replacing factory intake is recommend for performance applications. long tube headers with good wires in addition to this throttle body upgrade has increased my mpgs and power so far without a tune. im planning on installing a raylar intake and cleaning up my head ports soon to hit my power numbers. sound increase with all this done on stock system is minimal ### ⭐⭐⭐⭐⭐ Works well *by C***S on November 19, 2024* Looks like decent quality and it works well so what more can you ask for? ### ⭐ OK if it worked but QC is not good *by S***N on November 4, 2024* I work for a harness manufacturer and I'm an engineer. this adapter threw codes if the harness is jiggled. I depinned what I could and it is clear to me that whoever crimped the GT150 terminals on the 6 way throttle body plug failed to do the job with the right die set or wire strip length. This would NEVER pass my own QC let alone my customers. I bought all new materials and will build this myself with quality parts and tools. This thing is going in the scrap bin the only useful part of it is to see the schematic. As a bonus, it is a lot of fun to go into limp mode in the middle of traffic because some crappy terminals and tools were used. ## Frequently Bought Together - Michigan Motorsports LS1 to LS2 Throttle Body Adapter Harness - Plug-and-Play Drive-by-Wire Conversion for LS1 Vehicles - Fits C5 Corvette, CTS-V, and More - A-Team Performance - Throttle Body Drive By Wire 4 Bolt - Compatible With Chevy GM LSX LS LS1 LS2 LS3 LS6 LS7 Black 92mm - Body Bolt - Ls Intake Manifold - Ls1 Intake Manifold - Uses 6-Pin Connector - ICT Billet LS Throttle Body Adapter - LS1 3 Bolt Intake Manifold to LS3 4 Bolt Throttle Body DBC LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33 LSX 4.8L 5.3L 5.7L 6.0L Billet 551513 --- ## 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.sc/products/82602838-ls1-to-ls2-throttle-body-adapter-harness-plug-and-play](https://www.desertcart.sc/products/82602838-ls1-to-ls2-throttle-body-adapter-harness-plug-and-play) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-04-23*
