Behind every modern factory car stereo there is a wiring harness that connects the stereo into the electrical system of the vehicle. While this makes it easier to remove the factory stereo, the wide range of plug shapes and sizes used by different manufacturers can make it difficult to connect an aftermarket stereo. ISO leads work by connecting to the factory fitted stereo plug within the vehicle and converting to industry standard ISO blocks. These ISO blocks are compatible with the harness supplied with all aftermarket stereos and allow for a clean installation without the need to chop the original car wiring loom.

A quick word of caution; some manufacturers are known to change the wiring plug within vehicles frequently. This can result in a single model, across different years of release, having different ISO lead options with some crossover. The best way to find the ISO lead for your vehicle is to use our What Fits My Car? page. Should this return multiple options you have a vehicle where the required harness could one of a number. Should this be the case we recommend you check the information available on each option with regards the factory head unit models, or better still remove the existing radio and double check which plugs your vehicle uses. Our technical department are available by email to assist should you require additional reassurance.

What about vehicles with stalk controls? Well, if a vehicle is fitted with stalk or steering wheel controls using a simple ISO lead will remove their functionality. To keep these working with a new stereo you would require a stalk adaptor, the good news we have these for a wide range of vehicles as well. Please note that if you go down this route you do not need an ISO lead as this is built in to the stalk control itself.
