SOT / T-Harness Leads

Basically a SOT (Sound On Top) lead is an adapter lead, which allows you to convert your vehicle’s manufacturer wiring loom, into a universal adapter plug known as an ‘ISO’ (International Organization for Standardization) plug. This ISO plug is a standardized plug that aftermarket in car audio manufacturers use to make chancing products easier.

The SOT side of things is needed to convert your vehicle wiring harness into this ‘ISO’ plug, then back into another vehicle manufacturers plug to allow you to keep the standard stereo working in your vehicle with such devices as an aftermarket hands-free kit.
