Well I am on my way, I made up my first cabels for sale today. These simplify adding the OBC function to your Boxster . They have the actual pins that fit your Instrument cluster plug , so no forcing in a "molex" or other pin that could ruin your harness. These pins are the OEM pins that fit perfectly. All cables are hand soldered, Ohmed out, Hand wrapped to give you a complete harness that will blend in with your factory wiring. I apologise for the poor wrapping on the white harness, it was my first and I will correct. I have already designed a bench jig to assist in the wrapping procedure. All connections are soldered and crimped.
You will still have to have the OBC function enabled by a dealer or using other diagnostic software like Durametric.
Thanks
Dwight
