Reported cause
The bolt holes are the same from 996-991, the issue is wiring.
Leading evidence: 'wiring' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'wiring' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Install 991 seats in his 997' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I've just seen a post where a guy fitted 991 seats in his 997, so that must mean they will bolt into a 996.

Suggestion
You will need to make sure you leave that unhooked on the new seats and if poking around with power or a multi meter, you don't want to set off the airbag.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

As the title says. I have a lead on a set of 991 Carrera S seats that I could probably get for a decent price from my indy who converted a customer's car to a race car. I have a 996 Mk1 Carrera 2.
I haven't asked how the seats are optioned, but I'd imagine they're power/heated/etc (my own seats are power/heated/memory). I wouldn't expect memory to work, but I'd want heat/power adjustments to work, at least.
Is there any chance of making them work, or should I give up and stick to looking for 997 seats?
So I'm discerning this by looking at a 996 seat wiring harness and a 991 seat wiring harness for sale on ebay - the connections look to be different. If you were motivated to try this you'd have to figure out how to adapt the older 996 input to accept the "new" 991 plug. Maybe there is a way to remove the plastic connector and swap it to the new harness but I cant help you with any of that. We've got a few wiring mysteries going on here on other threads so maybe one of the electrical gurus here would be able to talk through the project with you if you wanted to pursue it further. Here are the pictures I'm looking at - 996 on top and 991 on bottom.
The wiring harness is different between the 997 and 996, so 991? Yeah... Doesn't mean it can't be done, just more of a pain in the butt. FWIW the 997 sport seats are WAY nicer than the standard 996 seats - I imagine the 991 seats are as well (I've actually driven a couple 991's but don't really remember the seats specifically...). Generally speaking all Porsche seats are pretty good, but we just can't leave well enough alone in the quest to make our cars "better"...
The bolt holes are the same from 996-991, the issue is wiring. Additionally, the 996 doesn't have airbags in its seats (at least the 986 doesn't...) but starting with 997/987, airbags were integrated in the seats. You will need to make sure you leave that unhooked on the new seats and if poking around with power or a multi meter, you don't want to set off the airbag.
Tom, I’d like to do the same thing on my 996, but I’m wondering how the guy that put yours in got around the seat occupancy switch? Retrofitted the original 996 sensors to the 991 seats? With 4-way seats all the power needed is for the single rake motor, so that should be easy enough, but the cushion sensors are the question here.
***I just did some checking and it seems the 996 does not have a seat cushion sensor, it’s in the seatbelt receiver, so I wonder if yours were changed as well?
