Was considering a 996 cluster upgrade for my 1999 Boxster base. There is some confusion as to whether the cluster needs to be reprogrammed to work in the boxster. I know mileage correction is necessary but there's talk about adding Vin # and enabling the volt and oil pressure gauges bla...bla. Some mention of Palo Alto Speedometer reprogramming but not sure what they need, I don't have original key codes... some say it is needed to reprogram the cluster. Any thoughts? thanks v

My wife and I did that swap with her 2001 base Boxster about... geez, 12 years ago.  She really wanted an oil pressure gauge.  :-)

 

I picked one up off of Ebay for $160.   We then took it over to our local instrument cluster shop (which worked on VDO) and had them change the odometer.  They didn't give us much of an issue about it, since we actually added 20,000 miles to it so it'd match our current Boxster mileage.  Then I came home from work one day, and the garage door was open, and my wife had the dash taken apart, the old cluster out, and was fashioning space for the new cluster into the housing with a dremel!   She had bits of plastic all over her.  It's one of those times when you just KNOW you married the right girl!  


My understanding is that the Boxster clusters differ, so for a 1999 the xfer might not work.   Here's an old thread discussing it:

Hi, Thanks for that thread, will give it a try. Seems no additional reprogramming was needed on the earlier MY's. Do you remember if you had to reprogram anything using a PWIS or PS2? thanks again v

Just tell them you have swapped clusters, they should be able to take it from there.

I did the cluster upgrade with the OBC upgrade using 2 window switches....pretty much plug and play ....all works with the exception of getting night illumination for to the switches. I read pins 3 and 5 are ground and hot respectively. I tried jumping 3 and 5 from the TC switch directly to the new switches...this did light up the switches but then caused the TC LED to remain lit at all times with the ignition off!! Can I just jump it from the cigarette lighter or ashtray light? Thanks V

You want a switched source - only on when the ignition is on. The lighter is always on.

 

There is a connector in the center lower console that has +12VDC always on, +12VDC switched, and ground. That is your best source.

Do a search here that connector has been discussed many many times.
