## Description

Reverse Wiring Harness for Select 2000-up GM Vehicles

Review: O.E.M. - I was in awe when I received these harnesses. Most of them are stamped on which wire goes where. Need magnifying glass to see them, but most of all, it comes with the wire color, and what it controls. There's 1 on the package and a more detailed 1 inside. The price was under $10, and definitely O.E.M.Grade, not what I expected, being the low price. The color and placement of the wires, are 90% accurate to the shop manual for 1999 to 2003 Silverado 4.8L, 5.3L. Although the Manual is 1999 to 2006 Silverados, Avalanche, Suburban, the wiring diagram colors changed a bit in 2004 to 2006 V8 Models. This 24 pin connector, plugs right in to your Instrument Cluster, making diagnosis of Cluster a breeze when bench testing with an OBD II, mid priced scan, read, and erase trouble codes. For experienced DIY Mechanics. 👍😎✌
Review: good - once wired in should fix my problem
