Retro-Fit Cruise Control?

I have started looking to buy a used 997 about 18months to 2 years old and have found a couple that come close to my preferred specification. One, in particluar has almost everything I require (and some things I don't) but doesn't have cruise control, which I have on two of my cars and which I find useful. Does anyone know whether it is possble to retro-fit cruise control and whether it's a complicated job?.
 
Thanks for the reply, Mark but I can't find the link to the technical article you mentioned. Could you re-attach it, please?
 
I think you may find an issue with the modern Porsches is that the wiring loom, a MOST BUS technology, won't have any of the wiring for cruise control, which may send you down the after market route. From what I recall the wiring looms are specific for each individual chassis number, depending on options. I'm sure I've read in the past of having to order a completely new loom against a different chassis number with all the options on your car, plus cruise, if you can find such a car, and that's really only when people have been repairing a write-off and adding features or converting something from LHD.

I have factory cruise control on mine, which is great, but I don't use it so much these days as the motorways are just so busy you're forever speeding up and down with the flow. The 997 is an easy cruiser, I'm sure you'll be fine without it.
 
The cruise control lever is a sepaprte bolt in unit, with a short cable loom to the wiper stalk above in the binnacle. You will need to replace the lower half of the steering column casing for one with the extra cut out.

Whether it is plug and play i don't know - i'll be interested to see the link to the tech article, cos i've been looking at this for my 987
 
To someone with my level of D I Y skills the retro-fit looks like astrophysics. I think I'll either buy a car with factory fitted cruise or do without it! Thanks anyawy.

I'll bet you £1 to 1p that the wiring is all in place and you just need to fit the lever and get the instrument cluster coded - which is where the problem lies. Wheras lots of independents can do this with a PST2 for the 986 and 996, I think you would struggle to find one with a PIWIS, which would be needed to do it on a 987 or 997.

On the 986/996 you don't need to replace the lower casing, as there is a rubber 'bung' that just needs cutting out to give a hole for the stalk. It might be the same on 987.

The link Mark posted is purely for 996 cruise retrofit, and doesn't apply to 997.
 

My previous car (z8) had cruise & I used it all the time when driving in a 30mph speed limit zone. Its missing from my 997 & at first I was a bit apprehensive in buying a 997 without cruise, but im pleased I did. The 997 power deliver is so much more smoother than my previous bmw's & I would say its not needed. Its easy to keep to the lower speed limits when in town, the problems occur when on the open road, trying to keep below 3 figures before the end of the slip road is a daily challenge especially where the slip road has a bend or two in it. It may come in handy in places like France where you could get your car confiscated for driving to fast.

I would say that even if you went for the basic Carrera with no options, you would still be a very happy man.
 
Thanks for all the replies. Have since bought the car - and found that it has factory fitted cruise control along with other things that the dealer hadn't stated.
