Howell EFI Is Your Source For Engine Transplant Wiring Harnesses – Tons Of Applications!

We all know Howell EFI for their longstanding and widely lauded electronic fuel injection conversion kits that can take virtually any carb equipped engine you can think of and easily turn it into a fuel injected piece but did you know about the vast array of wiring harnesses and kits for engine transplants that Howell offers? We’re talking LS swaps, big blocks, small blocks, LT series engines, and a whole lot more.

The benefits of a Howell wiring harness for your swap are many but the fact that these guys are creating their harnesses with OEM grade hardware and components, they are labeled, terminated, and designed to lay out and plug in are just a few. We know that not everyone in the world is doing an LS swap and so doesn’t Howell, that’s why they support so many engine styles and families out there right now.

Here’s the scoop from Howell! Hit the link to their site to learn more.

Regardless of the Engine Transplant, Howell Has You Covered

Wide Variety of Products for Amazing Number of Applications!

Marine City, MI…  Currently Howell EFI offers wide-ranging GM-style EFI conversions for many applications and harness conversions for any GM V6 and V8 engine from 1985 to present. For anyone not doing a complete carbureted to fuel injection conversion, we also cover the transplant segment with 30+ years of vehicle applications.

As an adjunct to our wiring harnesses, we developed complete throttle body and multi-port fuel injection systems. We combine proven GM electronic components, Howell wiring harnesses, two and four-barrel TBI and TPI units. These systems offer GM closed-loop fuel and spark control, and typical GM durability and fuel economy. With extensive development on both big-block (454/502 CID) and small block (350/400 CID) engines, these systems are attractive updates for both hot rods, production carbureted vehicles, and off-road four wheel drive vehicles seeking both performance and fuel economy.

Whether you are looking to do a TBI, TPI, MPI, CPI, LTI (90’s & current LT1), LS, Vortec, or EcoTec3 EFI conversion or engine transplant, look no further than Howell.



At Howell EFI, we choose to sell only the best quality components, and all are covered by a money back guarantee. For additional information, visit or call 810-765-5100. Howell EFI is located at 6201 Industrial Way, Marine City, MI, 48039.
