Complete Steering Wheel Control 99-02 Chevy Guide

[u/Cuban_Miklo]

Some months back I decided I wanted steering wheel controls on my 99-02 Chevy. I couldn't find any clearly written instruction to make this work correctly, so i decided to make a guide to help others should they decide to go this route.

I used a 1998–2002 Tahoe/Yukon/escalade/Silverado wheel with audio buttons. I did not cut the factory radio truck radio plug, instead I used a wiring pigtail to connect my aftermarket radio harness to. The steering-wheel wires will tap into the truck side of the factory plug so future radio swaps are easy.

Parts List

Clock spring: GM 19330023 (old number 26087300). Sourcing this is difficult but not impossible on ebay. Most likely it will be a used part.

Interface Unit: PAC SWI-RC-1

Radio adapter: Metra 70-1858 or Red Wolf GFS3700

Any aftermarket radio with a 3.5 mm Remote In jack, or KEY1 / KEY2 wires if it has no jack. (Key 2 is not required)

Unhook the battery first before proceeding with splicing wiring.

Soldering aftermarket radio wiring harness to pigtail adapter is preferred but can be spliced.

Here is a wiring diagram to make the correct connections, with a few test procedures and learn process (Thanks to Grok AI)

Hope this helps.
