Howell EFI, a trusted name in electronic fuel injection conversions since 1997, is expanding its lineup with new LS and LSA swap harnesses and components for Gen 4 LS-based truck engines.

“We pride ourselves in offering the most popular applications and filling in our product line for more complete coverage of EFI conversion harnesses. These harnesses are on the website now and are made to order," says Matt Howell, President of Howell EFI. "We do not make one-size-fits-all harnesses. We build the harness and offer ECM reprogramming to the customer’s spec here in Michigan."
Howell’s harnesses use genuine GM components and can be configured for both manual and automatic transmissions, with options for drive-by-wire or mechanical throttle control. Customization is key - whether it’s emission connectors, fan wiring, or gauge sender leads, Howell’s harnesses can be built with the extra length or cover options you need, including OEM-style plastic split loom or nylon braid sheathing.
