1995 - 2002 GM OBS Truck Wiring Harness Grounds and Where to Find Them (Chevy, Cadillac, and GMC)

In this video we go over GM service information for where to locate primary ground points to the engine, body, and frame for the factory wiring harness schematics on GMT400 old body style (OBS) trucks and SUVs. We will cover how GM does wiring component zone numbering, service bulletin wiring errata, ground location descriptions, ground location diagrams, and actual footage of each of the primary ground attachment points on both pickup and utility truck bodies. Location views are specific to either the 6.5L, the 5.7L, or the 5.0L V8 engines of these years. For OBS pickups the 1500s ended in 1998, the 2500s ended in 2000, and the 3500s in HD form lasted until 2002. The OBS Suburbans ended in 1999, and it was the first year for the Cadillac Escalade (which was based on the OBS GMT400 platform). And model year 2000 OBS truck models are limited to the Cadillac Escalade, and Chevrolet Tahoe Limited and Tahoe Z71. This video ONLY applies to OBS C/K trucks based on the 1988 era GMT400 platform, not the GMT800s that overlap 1999 thru 2002. The eBay and Amazon search links below are paid links, for which I may be compensated and earn a commission, if you choose to buy the parts and tools shown in this video thru them: While most of the ground attachment points are part of the wiring harness, there are a few braided strap style ones that can be replaced separately. They vary in length depending on the engine equipped, and the alternator amperage output rating (and whether the truck had single or dual alternators originally). Measure your original one for the particular ground straps here. Ground strap G111 (GM 12157175(15"), GM 12157181 (13"), GM 12157185 (18")), and ground strap G110 (GM 12132154, GM 12157174 (24"), GM 12157178 (18")): https://ebay.us/ALGqvk GMT400 type GM factory C/K truck service manual I used in this video: https://ebay.us/WXryxg And if I've saved you some $$ here, consider some coins for the coffee tip-jar! https://ko-fi.com/drshock 1995 1996 1997 1998 1999 2000 2001 2002 Chapters: 0:00 - Service information zoning overview 1:47 - Service manual errata example 6:55 - Ground location text descriptions 8:00 - Ground location diagrams and video Corrections: 19:27 - I should have said that ground is G111, not G110.
