Hi guys,
As i'm about to do the OBC hack on my MY03 with one rocker switch I have read as many available guides and posts and I must admit that got a bit confused by some details, which I'm confident you guys know in your sleep.
My goal is to do the hack with only 1 rocker switch and thereby being able to control two of the pins. I dont care about the speed gong, but would like to be able to scroll through the different functions and sometimes maybe reset the "average values".
This matrix can be found on Pelicanparts.com:
Boxster 1997-2000
Connector Pin #2 Gauge Cluster Pin #20 Select Mode Down
Connector Pin #3 Gauge Cluster Pin #21 Speed Alert/Gong
Connector Pin #4 Gauge Cluster Pin #22 Select Mode Forwards
Connector Pin #5 Gauge Cluster Pin #25 Select Mode Backwards
Boxster 2001-2004
Connector Pin #2 Gauge Cluster Pin #23 Select Mode Down
Connector Pin #3 Gauge Cluster Pin #22 Speed Alert/Gong
Connector Pin #4 Gauge Cluster Pin #21 Select Mode Forwards
Connector Pin #5 Gauge Cluster Pin #24 Select Mode Backwards
Question 1: Is "Select Mode Down" the same function that in other guides is described as "Mode Up" - and that it's only a matter of viewpoint if it is scrolling up or down? I mean, could it just be called "Mode Next"?
Question 2: If the above button scrolls through the different functions of the OBC, what does forward/backward do?
Question 3: Which one would act as "reset" for the average value functions?
TLDR version: If i can connect to only two pins, which ones out of #21, #22, #23 and 24 should i choose to be able to scroll and reset?
Thanks a lot in advance!
