Aftermarket / OEM Heated Seats

Recommended Posts

Hey, I have been thinking about installing the aftermarket Heizgerat Setz carbon fibre heated seat kits sold by heatedseatkits.com (among others) and have a couple of questions.

First, can anybody confirm they fit?

Second, I would like to use the OEM switch (and relay if, as I presume, this is required). I believe I cannot wire directly from the OEM switches (which are momentary contact) to the aftermarket relay or switch (which is continuous contact). Does anybody have the wiring for the aftermarket panels????

I've read Dennis Vogel's DIY obviously, but am also wondering about the wiring coming out the of the OEM seat harness/relay? As well as any other advice....

Has anybody done this?

Here's a lower cost solution.

I wonder if the car has the wiring harness in place for it.

First, I believe that the wiring harnesses from the factory are unique to the car and it's make-up, meaning that if it wasn't slated to have heated seats the harness will not be there for a hook-up. Second, I was told that the Porsche heater switches are different that normal and won't work on an aftermarket system. Third I had aftermarket seat heaters installed a couple of years ago and it was fairly in-expensive and they have performed well. As a bigger person, when they removed the seat covers to install the heating pads I had them flare the bolster wings a littel and it gained much needed kidney room. Ed

What Ed said: "I believe that the wiring harnesses from the factory are unique to the car and it's make-up, meaning that if it wasn't slated to have heated seats the harness will not be there for a hook-up."

The wiring harnesses are unique to the individual car, controlled by the initial build sheet.which is in return controlled by the initial order. FWIW, Porsche does not build any car "on spec". The cars you see on the showroom floor are usually ordered by the dealer's sales manager....to be sold "on spec".
