Overview

The Rywire K24 Milspec Engine Harness is a Version 2 harness designed for universal chassis and routing preference. This harness can be routed through the center or to the right on the firewall, ideal for RHD customers but also suitable for LHD chassis and aggressive exhaust manifolds. It features Mil-Spec Teflon coated wire with ETFE insulation, standard factory wire colors, and a maximum heat rating of 200°C. The harness is loomed with Raychem DR-25 heat shrink, uses adhesive-lined junctions, and features pneumatic crimped connectors. All heavy interference circuits are protected and grounded, and each harness is 100% quality tested for pin-to-pin and resistance checks.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
