In this one example, it looks like "LEFT" and "RIGHT" being part of the abbreviation. I understand the wire cross-sectional area as the middle number, and the color of the insulation as the bottom.

I tried searching the abbreviations section on TIS and could not come up with ANYTHING. But I do believe its an acronym for something. Is it perhaps the terminal name?
Like I said on my earlier post they are signal types. NewTIS has a different structure than original WDS which has these signals listed.

For example NTCHL comes from NTC (NTC resistor=typical temp sensor) Hinten (rear) Links (left).

There we go--that's the answer I was looking for! That's freakn awesome! Sweet! :thumbup:

Okay...so then I can use WDS here and search that signal wire:

I'm having a hard tire figuring out how the heated steering wheel works.
Is there a way to program it to heat up to higher temperature ?

The only option I've ever heard of regarding coding it is some cars you can have it come on below a certain ambient temp. I've never seen a temp option such add the seats have. Certain cars you can code the temp levels of the three stay heat options. I don't think the wheel even has a thermistor to keep track

I'm not a pro with diagrams but was wondering if there's a way to replace the modulated signal to the heating element with a constant power supply when pressing the button

The steering wheel doesn't seem as warm in warmer weather but it's fine when it is cold. This should probably be in it's own thread.
