DIY ISO Car |
The APP series of harnesses are designed to plug directly into the pre-existing factory radio plug/s of your car, leaving you with a set of female ISO plugs on the other end. The female ISO plugs can then be plugged straight into either an "APP8" series plug (which then simply plugs straight into the back of a head unit) or straight into an original factory head unit (if unit is using ISO male plugs).
