Electric Seat Retrofit 2000 3.2S?


just registered with your great forum. i've been researching boxster info for a wee while now and am about to purchase a 2000 year 3.2s tiptronic which has accident damage.

please dont flame - it's the only way i can afford to get one and i will repair it back to pristine condition and keep / drive for many years.

as soon as i get the car i will post photos and start a chronology of the repairs in the hope that it will help others.

i'm pretty handy mechanically, feel i can tackle anything, have very good garage facilities at the bottom of my garden and am more than happy to seek professional help where needed - i'm not proud to the point of irresponsibility.

the car i'm buying is pretty well specified, but the one thing i'd like above the spec it has are power / heated seats - it has electric back adjustment but i'd love to add all the rest of the electric adjustment.

clearly i'll need to source appropriate donor parts.

has anyone achieved this and is able to provide advice and guidance?

Welcome to the forum and good luck with your restoration ! I look forward to hearing about your progress...

Here's a good thread regarding heated seats ( look at MNBoxster's post ) :

I've had both kinds of seats

And never thought the fully motorized made that much difference. Once you juggle the seat into the position you want, it stays there until the mechanic changes it.

Might be worth doing if you had multiple drivers constantly switching off on the car.

There are wiring diagrams available.Link

I just did this retrofit, and can walk you through the steps. Its very simple actually. Currently, you have one 30 amp circuit to your seat to power the backrest motor. The full power seats you will buy will have a memory controller under the driver seat. The passenger seat is plug and play, the driver seat is not. You have to run power, which is comprised of 3 circuits, to the memory module, which in turn powers the seat motors.

You will re-use the 30 amp you have, and have to add two additional 7.5 amp circuits. I will post images of the pin outs on the memory controller so that you can power it. You will also have the opportunity, if you want to do ALOT of wiring, to add seat memory, which will also control the mirrors.

If the seats your purchase are heated, you will have to run the wiring for that as well, of which there are plenty of tutorials online that will walk you through that.

this is really encouraging - thanks all.

i do consider this worthwhile since the car will have a second driver - my wife.

the memory functions will be essential and very worth pursuing!

lots of wiring holds no fear - i love the challenge and do possess a reasonable level of technical skills.

i needed peace of mind that this was achievable and you've given me confidence.

all pinouts, etc will be greatfully received to help estimate and plan the job.

i get the car at the end of the week so i'll know a lot more then. i do have some real stuff to deal with at the front end - wing / bumper / rad / etc.

once i have that out of the way and the car is on the road and legal, the seats will be my main task.

what a fantastic community.

i'm off to ebay to get a cheap digital camera that will stay in the garage to keep an accurate record of my activities. this will allow me to share what's happening with anyone who's interested.

thanks again
