I just swapped the stalk from the 4 stalk to my 3 stalk. Buy the harness from PDwight.

Hi Folks.
I just gone through an OCB / CC upgrade in mine 2004 2.7 986. Went fine, but only partially :confused:
OCB works while CC not.

When I turn the key (before starting the engine) all LEDs are on. Also green LED from CC appears - it wasn't before the up. But when engine is on nothing happen, pressing the button on the stalk doesn't turnt the light on of CC.

I'm in a fix...
Could it be faulty 4-stalk controller or some connection issues ?

Regards,
Tomasz

Cześć Tomasz!

Tell us exactly what you did. Did you reprogram using a PIWIS?

I did the full install on an early model, including adding the pedal actuator, sensors, and wiring. I then did a quick write-up on the Porsche Club Poland forum.

The first time I did this, I was able to add the OBC stalk (removed from a donor 4 stalk) to the 3 stalk in the car, without having to remove the steering wheel. It made the process much easier.

Hi Folks,
Thank you for your response. Finally I found the fix.

After installing all HW modifications I completely forgot to activate CC in 2 places: Instrument Cluster and DME. I've only activated CC in Instrument Cluster and that caused such behavior. Activating CC in DME as well solved the issue :)

Greetings!

98 cruse control...
 
I've got the stalk, and box under the dash ....

I'll never use them (my ecu will not support it, swapped motor)


worth anything to anyone?

thx, matt

p.s or should I bin it all.

steved0x 02-17-2016 07:37 AM

Don't bin it, put it for sale, I have actually seen people ask about it before. I bet there is someone that wants to try to add CC to their 2.5 Boxster.

For anyone looking to do this upgrade, I saw this stalk this morning on eBay. All you care about is that he OBC stalk works which it says it does. Just remove the stalk and add it to yours. I don't have any affiliation with the seller, I just thought I would pass it along.

I have the harness to add cruise control. The VW wires/plug as described by Pelican. PM me if anyone is interested.

I've purchased an OBC stalk which was previously retrofitted but they had cut off the original connector and installed their own. Not a worry, I can make a harness to suit. But, what are the pinouts for the stalk?

I found the following on Pelican Parts:

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

I'm a little confused at "Speed Alert/Gong". The stalk has Select Up and Down, Enter (push?), Escape (pull?)

I've connected a multimeter to the earth and each pin and have found that on mine is:

Red = Down - So Pin #2, connect to #23 on cluster
Yellow = Up - assuming Pin #3 then and connect to #22 on cluster?
Blue = Push - So Pin #4, connect to #21 on cluster
Black = Pull - So Pin #5, connect to #24 on cluster

Can anyone please confirm?

I am going to upgrade my Boxster S 2002 ROW with CC stalk, reading sevral treads I found two verison for wiring refere to model yeare 2001-2002.
On the majority there indication to link a wirw from the cluster to DME on soem other is wrote this not necessary doe the fact that after 2001 new instrument cluster does not require this conenction.
Someone as more details?

Pdwight 02-21-2017 03:16 PM

No need to connect to DME
 
Or at least on USA cars, I have manufactured many harness to retrofit a 4 stalk. You need a common or ground and the wires that go to the instrument cluster....no need to run any more wires.

Nik64 02-25-2017 03:25 AM

Hello
I just installed the 4vstalk on my car 986 my02 the obc works fine, the cc works but instrument light light does not switch on.
Someone knows why?

Anker 02-25-2017 04:53 AM

Did you check the bulb?

Nik64 02-25-2017 11:41 AM

The cluster as equipped with led no standard bulb, so I did not open it

I finally completed the OBC and CC hacks to my '01 Boxster back in February.

I bought a used 4-switch stalk from Parts Heaven that was in excellent shape. I also purchased Pdwight's OBC harness which is "first class". I made my own wiring harness for the CC functions; followed the guide on Pelican which was a great help.

Finally activated everything with my Durametric Pro. Both the OBC and CC functions have been working fine ever since. They are great!

IMHO, these are two of the best upgrades available for Boxster's without OBC and/or Cruise Control.

Pdwight 04-10-2017 06:03 PM

Thank You for the kind words
 
I try to make every effort to make my harnesses the very best hand made product possible.

BER 04-20-2017 06:03 PM

IMHO, you have accomplished your goal!

Thanks for your first class OBC harness!

I finished my winter project of installing the 4 stalk controller so as to enable cruise and the OBC. I followed the directions as laid down in "101 Projects for your Porsche Boxster", "986 Bentley Service Manual" and the web site Renntech.org which has a wealth of information for this upgrade. Now I just have to get to an Indy Shop/Dealer to activate both through the computer.

I took my time for fear of breaking something and this took two days, no breaks. If I had to do it again probably 4-5hrs. My garage temperature was around 5 to 6 C so plastic parts aren't as pliable.
When removing the instrument cluster all the documentation tells you to lift straight up after removing the 2 screws behind the telephone speaker and the hazard flasher. They don't mention that there are 5 plastic tabs helping to hold the instrument cluster to the dash. Likewise with the Trim Ring around the steering column and the dash, it is secured on top with 2 screws and under the steering column there are 2 plastic tabs, lift straight straight up.

The condensed wire plan is;
2003-4 Boxster Cruise:
Plug C (Grey) on the Instrument Cluster Pin 17 - Stalk Connector Pin 1
Plug C (Grey) on the Instrument Cluster Pin 4 - Stalk Connector Pin 3
Plug C (Grey) on the Instrument Cluster Pin 1 - Stalk Connector Pin 4
Fuse B7 - Stalk Connector Pin 2
2003-4 Boxster OBC:
Plug C (Grey) on the Instrument Cluster Pin 23 - Stalk Connector Pin 2
Plug C (Grey) on the Instrument Cluster Pin 22 - Stalk Connector Pin 3
Plug C (Grey) on the Instrument Cluster Pin 21 - Stalk Connector Pin 4
Plug C (Grey) on the Instrument Cluster Pin 24 - Stalk Connector Pin 5
Earth (ground) - Stalk Connector Pin 1


so let me get this straight.
If one is to install the 4-stalk, some wires are "doubled", in other words, connected to same pins from the stalk, but different on the gray one (C plug).
Pin 1 is ground and goes to Pin 17
Pin 2 goes to Pin 23 and Fuse B7
Pin 3 goes to Pin 22 and Pin 4
Pin 4 goes to Pin 1 and 21
Pin 5 goes to Pin 24

Is that right?

Base 2003.
I hope to get clarification soon as I am in the middle of the project...

PLP 10-05-2021 03:09 AM

OK, never mind... I figured it out myself. I just needed a night of sleep.

Of course those are two different plugs. Somehow when I read initially the project it sounded to me like it is enough to get the 4-stalk and 5 wires, plus the plug.

Yes, that is true for the OBC. There was no plug to purchase for Cruise Control.

OBC has a 6-pin connector where only 5 are used.
CC has a 4-pin connector and all of them are utilised.

Therefore, if one wants to do both projects at the same time - you will need overall 9 wires and preferably 16 plugs (one is ground while the other goes to B7 fuse) .
