Description. Modification of Stock Engine Harness. If you’ve acquired an LT1, LSx Gen 3 or 4, or Gen 5 (LT1, L83, L86) style engine that came with a wiring harness on it, and you feel that the length of the harness to the ECU, and the look of the harness will work fine for your project, then we can simply modify it to be a stand alone engine management harness.
