Installing A New Engine Wiring Harness Into My 2015 Chevy Tahoe

[Rev1]

Hi Everyone,

I'm trying to install a new engine wiring harness that I bought to go into my 2015 Chevy Tahoe. I've tried buying a month subscription to SurgeCharge, Alltadata, and Identifix and none of them have any sort of installation guidelines nor any diagrams of putting in the engine wiring harness. Does anyone have any diagrams, pictures, or step by step guides on how to install it, or know of where I can buy any diagrams, pictures, or step by step guides, or even if you have any diagrams, pictures, or step by step guides on how to install it? Any advice and help would be great.

I attempted to create a step-by-step for the GMT 800, but I think it was more like a FYI, LOL.

How to re-loom your ECU/engine/transmission wiring harnesses

Alright, my first real thread :) So the wiring harness loom was missing in a lot of places in my 2006 suburban 2500 LQ4 2wd. I bought the truck like this and the PO was kinda a car guy, pretty clean so I don't know what happened. I guess age is also part of it. Anyways, I'd been putting it off...

Should be very similar to the GMT 900. The rear head ground and other ground near the oil pressure sender were probably the worst part, aside from being under truck and feeding the harness through transmission bellhousing.

Let me know if you have any questions.

Edit: Oops, just realized your truck is a T1XX generation.

No worries. yeah it's a 2015. I've spent hours searching for some sort of guide to install the engine wiring harness, but can't find anything.
