The VAG diagnostic gateway cable harness is the consistent further development of the well-known VAG OBD cable. One end has the 6 and 12-way Molex connector for the MFD15 display, the other end is a Y-cable with which we can loop the display into the gateway. With this wiring harness it is possible to keep the diagnostic socket free and to take Can High/Low as well as 12V ignition plus and ground directly from the drivetrain instead of the diagnostic bus. The advantages are obvious: data retrieval is accelerated and you can also use this wiring harness if you have a freely programmable ECU installed in your vehicle.
