Description:
Hi,
I just bought a 2400 mile Cayman GT4 on BAT .
While I know it is a longshot, I would love to have Carbon LWB seats instead of the sports seat plus. Seats have yellow stitching.
A swap plus whatever a fair price is would be ideal but I would also gladly purchase great condition LWB's.
I am in Gainesville, Florida so this deal would need to be within 200 miles or so.
Thank you,
Brian

Have you search to see what's needed for a car with buckets to make the sofa seats works with no lights and the 18 way fully functional?

I found this in old post on GT4 forum. Are you interested in making a swap??
I did the swap with the OP (great guy to deal with) and was there when they did it. The swap itself was easy. No need to change harnesses or plugs, or get new ones. Each cars’ harness looked alike (one exception below) with the exact same plug on each car/seat. It was simply a case of pulling the seats out, swapping them and plugging the harnesses into the plug on the seat.
Only difference was that the car with the 18-ways had twelve wires in the harness while the LWB car had ten. The two additional wires lead to a small box on the bottom of the 18 way seats that the LWB seats did not have. Initially, we did not know what it was.
After plugging the seats in and testing them we found that the 18 way’s worked perfectly in the car that had the LWB’s before. No airbag or other error codes. Perfect plug and play. The programmer also used the Porsche software to validate that the airbag etc. was getting correct signals. All good.
Once we plugged the LWB’s into the car that had the 18 ways before, the up/down seat adjustment worked; however, the car threw a number of seat diagnostic codes. This, in combination with consulting the wiring diagrams, showed that the small box under the 18 way seat, with the two extra wires, was a seat diagnostic unit that would notify the car if any of the adjustment functions fail in order to generate an error code. Since the car now had LWB’s and did not need it any longer, we simply coded it out.
Since the car that received the 18-ways, that had the LWB’s before, does not have the connector wires for this seat diagnostic module, it will NOT throw error codes if seat adjustment function fail, you’ll just know it doesn’t work anymore, when it doesn’t work anymore ;-)
The complete swap and coding process took about 3 hours start-to-end. It was much less painful than I was prepared for.
