These engine wiring harnesses are designed to make your engine transplant effortless. Each new harness contains in-depth application-specific instruction sheets, clearly marked factory GM connectors, labeled GXL jacketed wire, GM color coding, and pre-fitted corrugated slit loom for an extra value and professional look. All un-needed emissions wiring is eliminated to make the install as simple and reliable as possible. Made from premium grade GXL jacketed automotive wire. Most wiring is larger gauge than stock application for durability. No splices to reduce points of failure. All primary grounding is done at the head or block and grounding points are isolated from each other to reduce electrical interference and minimize ground looping. Harness wiring matches GM wiring configuration and jacket colors follow GM color coding for easy identification. All electrical connectors are made by Delphi or Packard and are direct fit for GM cars and trucks. Can be installed to run engine in 20 minutes, but figure 4-6 hours for a professional installation. OBD1 diagnostic port for connection to scanners and tuning tools. Made in the USA. By Johnny on October 17, 2017. Used for a tbi engine swap into older truck. Made the swap simple. Yes, I recommend this product. Nice wire harness, made life easy. By Mower man on September 17, 2017. Few branches could have been longer, had to lengthen a few sections, but overall, very helpful. Saved my swap, I’m n mechanical engineering don’t need to be. By project Roosta on August 13, 2017. Everything labeled, and in the right place. Made the conversation from a carb chevy 350 to throttle body chevy 350 like a pro.. And I get bragging rights that I did the swap. I didn’t go with it in the first place. By Mike on July 31, 2017. Installed with no issues. Made hooking up my donor engine easy. Exactly what I needed, without the useless extras. By Logan’s Dad on June 23, 2017. I, (Mostly my ten year old Son, but he lets me help some)put a freshened up 1991 TBI 454 in a Military Humvee. Like most, I’m on a budget. I had orignally intended to salvage the factory harness, but eventually came to my senses and shopped around for a new wiring harnes. I definitely got the most bang for my buck with this one. I wasn’t expecting anywhere near the quality that I received. Nor was I expecting everything to be so clearly labeled. If I ever put myself through another diesel to big block swap, this will be the first part I order. Easy To Set Up. Related Items / Suggested Parts.
