This cable plugs into the ICT control box and into the 3.5mm socket on the back of Sony or Pioneer head-units that are steering wheel compatible.
This special interface has an external resistor ladder built into the cable. This means it can be used on both older model head-unit with 5volt rest voltage on the middle pin of the 3.5mm jack socket and with newer 3.3volt units. It is also more stable against voltage drops in the cars system caused by poor earth points or earth ground loops.
This special patch lead is to be used with InCarTec interfaces with V2.35 and older software versions, this can be identified by the sticker on the interface box. It will be a WHITE sticker with the software version printed on.
