3-Spoke Tiptronic Steering Wheel - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Okay, so I bought a 3-spoke tiptronic steering wheel for my 5-speed manual with the intention of using the tiptronic buttons as a way of controlling my DNX6190HD.

It is outlined in this guide here:
Steering Wheel Stereo Control DIY

However, the guide does not detail a crucial step. Shown in the back of my wheel are three connectors:

The guide does not label which one is the horn, which is the airbag, and which is the tiptronic. Any help is appreciated.

take out the bag and use a voltohmeter to do a continuity check. takes less than a minute without the bag.

Yea, I don't have a DMM. Was hoping someone here could tell me. Guess I'll go buy one later.

My second question is, will I still need an adapter of some sort or could I wire the buttons (each with a different resistance) straight up to the light blue/yellow wire, and program it through my head unit?
