Seat Change Question

[whs]

I've read through the many postings regarding seat changes, but didn't find an answer to my question. I currently have supple leather, full power with memory seats in my 99 996 cab. The seats are showing a fair amount of cracking. I understand that on the early model 996s Porsche used a thicker leather that was subject to this type of cracking if the seats were not conditioned regularly. Anyhow, I have found some seats from a 2003 (post recall) 996 that are full power, memory but also have lumbar adjustment and are heated. I think I am correct in thinking that to use the lumbar and heat I would have to do some additional wiring. My question is if I don't want to connect the lumbar and heat is this a simple plug and play switch or is the entire harness different and the whole thing would need to be rewired? Thanks.

This is a site with instructions for adding heated seats in a Boxster, I used it for my 996 with slight modification. It will show you what is required for wiring, switches and relays to use the heated seat function (which by the way is great if you live in a cool/cold climate). As for the lumbar support, this is just a local function (i.e. within the seats) with a switch on the side of the seats so you probably just need to bring power to the switch/pump. I will have to look at a wiring diagram to confimr this.

Thanks for the link. I had reviewed it while I was searching for my answer. I would definately wire for the heated seats in my case. One thing that I'm not clear on is for a 996 the tip switches go in the batwing. Does that mean it is not necessary to remove the center console? It appears that the only reason it gets removed is to run the wires to the switches on the Boxter. That being said, I really need to make sure that I don't have to re wire the entire seat to get the functions I already have to work. Thanks.

In a 996 you don't need to remove the rear center console as the tip switches go in the batwing. I guess in a coupe you could use the open switch positions by the ashtray, but in a cab these are taken by the rear window switches. You can get a bat wing with the two switch positions, or four positions if you have other fundtions you want to add. NOte that when you buy the tip switches there are two finishes, glossy for older cars and matt for newer cars.

I will look on my wiring diagrams to see how power is supplied to the lumbar controls. Good luck!
