For Cuise Control, does Boxster 2002 require to run the wire from the stalk to the trunk?

Please advice

I think is does but there are more knowledgable people on the subject than I am.

It is actually called order type and get to it by going to Vehicle Type (Boxster (986) then to DME -> then to Vehicle data. Then scroll down to (and highlight) Order type. Press F7 to change the order type to 986xxx (yours is likely blank).

xxx being:

310 is normal Boxster (986) for USA

320 is 986 S car US model

330 is 986 Anniversary US model

Press F12 to confirm the change.

(these are from my 996 - but you get the idea)

You will need to disconnect the tester - turn the ignition off. Then reconnect everything and set the cruise control on in both the DME and instrument cluster. Done!

I appreciate it. Hopefully we can try it tomorrow.

Thanks again

Ohio Valley Region PCA had a tech session yesterday at one of our Porsche dealers. The Porsche tech was nice enough to try your instructions on how to turn on the cruise control. He was skeptical that it would work. After trying it wrong the first time and then following your instructions, step by step, he was able to get into the part of the program to turn on the instrument cluster. We got a cruise control indicator light to come on and after taking a test ride, the the cruise worked perfectly. I want to Loren for his help getting this cruise working. If I couldn't I probably would have sold the car and looked for another. Thanks again to Loren and the technical forum.

Did you have it turned on in the cluster and DME both? (using a PST2 or PIWIS tester)

I can't find my or your last post but to reiterate. I have a 03S Boxster and couldn't get access to the instrument cluster with the programmer at a Porsche dealer or at my independant Porsche mechanic's shop.

You replied that some 03 and 04 cars left the factory without the model code in the DME. I talked to my indendant Porsche mechanic and to two Porsche dealer without finding anyone who knew what the model code should be. One suggested that he might be able to take a code off of another 03 Boxster that has an OBC but wasn't certain that it would work or if it did what it might do to the future information that might be needed to retrieve from the DME. Can you tell me what the code should be or where it might be found? Will this effect the DME at a later date or void the warrantee? Also the dealer's mechanic indicated that there are two different part numbers for a Boxster instrument cluster. The one without an OBC is #98664121302 and the cluster with an OBC is #98664123302. Tommorow we have a regional Porsche tech session at one of the dealers. Possibly I they will have more information for me then. If I had the model code I think they would program the DME for me them. If not I know either independant mechanic or the other dealer is willing. Thanks for your help.

I received some information from the forum about added cruise control to my 03 S Boxster. The information indictated that all the connecting would be from the cruise control stalk(I have installed a four stalk unit) to the grey connector on the instrument cluster. I had the cruise control switched on today after wiring as per the diagram. Unfortunatly the cruise didn't work. Does anyone have any idea what the problem might be? I rechecked the wiring and it is correct and all the connections checked out.

I have a 03 Boxster S and have read just about all the posts up to this point having to do with installing cruised control in my car. I have already purchased the four stalk switch. Most of the posts talk about 2000 to 2001 cars. Is there anything different about a 2003 installation?

Thanks

Rich

I did the mod on my 03S, went from a 2 stalk to a 4 stalk. It's pretty straightforward, make sure you have all the wires (the 009 and 010) and assemble the harnesses in advance and you're ready to go. Make sure you have a 24mm socket for the steering wheel nut and put the connectots in (on the yellow cables) with the spring clip outwards, then you have a chance of removing them if needed and they will not short on each other.

Oh... I should mention... my car is Tiptronic so no clutch switch, not sure if that is needed or how it is done, sorry.

Thanks for the info. Can you tell me if the description of the hack posted by Ed B is correct for a 03. There is some reference about how the 03 might be different than the 02 and earlier cars. I want be be sure that Ihave all the information straight before I take my car apart again.

Thanks

Rich

Now, about the clutch and brake interlocks...do they need additional mods to function like factory, or is that performed through the DME? Can you help me with that? Thanks.

On all the cars I have seen the clutch switch is already in place and wired up. The brake disengage function comes from the brake light circuit.
