  • Plugs Into Your Factory LT1 Harness Without Modification
  • Harnesses Are Thoroughly Labeled

Why Use An Adapter Harness?
Most pullout LT1 engines already come with the factory engine wiring harness, and PCM. Usually, the factory harness is thrown out and a new aftermarket harness is installed. The key differences between an aftermarket harness and the original come down to fuses/relays, and labeled wires to guide you through the install.

Instead of throwing out the factory harness, our kit plugs into it and adds the necessary relays, fuses, and wiring to properly install your LT1 in your project vehicle. Once installed, it will offer a cleaner, more attractive solution than an aftermarket harness. Installation instructions are included.

Note: Due to the differences between harnesses across different applications, it is EXTREMELY IMPORTANT that you order the appropriate adapter harness for the vehicle, year, and transmission that your factory harness was originally intended for. For example, if your engine and harness was taken from a 1994 Camaro with an automatic transmission, you MUST use our 1994 LT1 Auto Adapter Harness.

Add On Options: Harnesses are prewired to work with our optional plug-in VATS bypass module (part number VATS-055).
