OBC Hack Help - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I do think your problem is directly attributed to the choice of switches. You may need to turn the OBC off at the switch, just like you would if you had turned on the heated seats. It's worth a try. Otherwise, I'd pick a different style switch like the key switch that's either on or off.

Hi,

The Heat Seater Switch is the wrong type. The Seat Heater switch is a DPDT (Double Pole, Double Throw) MOM-ON-OFF-MOM On to accomodate the 2 Heat Settings. What you need is a SPST (Single Pole, Single Throw) ON-OFF switch such as a TC, Lock/Unlock, Conv. Top, etc.

Why don't you just add the 4th Stalk because you won't be able to do resets with a single switch, only scroll.

I bought an entire 4-stalk unit from LA Dismantlers for $100. It was a pristine 4-stalk unit from a 996 (same-same, except the 996 has Auto Cruise Control) and they sent it completely assembled w/ Trim Pieces.

I removed the 4th Stalk (it just screws to the other three - the only one which does and not available from Porsche separately), added to my existing 3-stalk, swapped the escutcheons (3-stalk to 4-stalk) and sold the resultant 996 3-stalk piece on ebay for $135 + S/H - got my switch for FREE and netted $35 on the deal, enough to pay for the VW Motec Connectors and Wiring Harness, just to give you an idea. Hope this helps...

Happy Motoring!... Jim'99

I switched the switch and everything is working perfectly now. Thanks for the help. Maybe in the future I will opt for the 4th stalk. I'm not that strong at wiring projects and the install is somewhat intimidating to me.

I would do it for you if you were in San Jose.

For others. There is a list being started. http://www.renntech.org/forums/index.php?showtopic=13779

Hi,

Without telling them you plan on doing the OBC Hack, take it to a Dealer and ask them to give you the Temperature display. Many will do this as a courtesy, or include it gratis with other service.

They want to Wet Their Beak at every opportunity, so if you tell them you want to do the OBC Hack, they will want their taste...

ummm I did the dash switch and it resets just fine when you hold it down.
one push cycles through the options, hold it down and it resets. The only thing it cant do is set a speed for the chime to go off.

I followed the hack instructions from rennlist

weird

Vince,
What OBC hack procedures did you use? I have a 2003 S and have been tempted for some time now to add the forth stalk and activate the OBC. I have read some of the other posts where later model boxsters, usually 03 and newer don’t gain all the OBC functions. Does your function like a normal OBC?
