Apologies for the needy first mail.

I have 2005 997 3.6

I managed to completely ruin the passenger seat.

No problem I thought, straight on to eBay, buy a couple of new seats, 4 bolts plug them in, i'm golden.

Only I am not.

The passenger seat works fine, the driver seat however doesn't. Not a peep - as in totally stone dead.

I swapped the fuses, and plugged in the old drivers seat. All seem fine.

A cursory glance at the pins in the plug/socket (comparing the old to the new) is they are indeed different. (The brown and red cables shifted)

Now, the new seats have all sorts of electrical add-on's my old one didn't. Memory, fully electric, heated seats. (I appreciate the heated bit won't ever work and it doesn't bother me.)

Is there a wiring layout? Or an adapter? Or should i just lie in front of the car and hope someone puts me out of my misery? :)

Any help will be gratefully received.

Will.

Hi,

All you need to do is get 12 volts to the seat adjustment circuit. All the controls are on the seat proper. So, you will have to locate ground and 12 volt wires in both the car and the seat. The car is easy. Just use any DC volt meter. The seat is a bit more complicated. Best is to take a 12 volt battery. Connect the negative to one pin and then try the positive on each other pin until you hit the combination that makes the seat adjustments run. Mark the wires, cut off the connectors and crimp on insulated male and female spade lugs. If you get the seat heater switch for the dash you can probably also make the seat heater work. I suspect the wiring is already there but I am not 100% sure. My guess is that Porsche uses the exact same wiring harness in all these cars. Also there is a switch in the seat that makes the car aware of an occupant. Turning on seat belt sign. I suspect you won't miss that!!
