This is a Motorola IHF1000 carkit harness - part number 3042260Z03 - for a Motorola IHF1000 / IHF1500 / IHF1700 carkit. This harness features the 18pin connector to the later versions of the IHF Electronic Control Unit (the blue box is about 2x6 inches, as opposed to the earlier style of IHF1000 which used a 4x6inch ECU with a 32pin connector) as well as an 18pin socket connection to the VDA-standard handsfree / PSE / carkit connection harness found in some Saab and other vehicles. This harness is an OEM part for a Saab bluetooth handsfree kit solution. Use this harness to replace a damaged one in your vehicle, or to start fresh on an install to move your IHF bluetooth carkit into another vehicle. I have a mobile electronics installation business and use my Bonanza booth to sell off excess inventory. Please feel free to send a message if you have further questions about any of my items or a question about a handsfree adapter harness for your specific vehicle. Thanks for looking!
