Hi there! My first question on here after lurking for a while. Of all the options possible on the 987 - I'm really happy with my spec, but would very much like to have heated seats in time for winter 2017. The cost of wiring and sourcing parts to do this to factory spec isn't realistic. I have a really good set of sports seats with the optional crest embossed so finding a set as good, with the heating elements, plus all the parts, coding etc. let alone buying a new HVAC module with the stock switches. Meh - too fiddly. So I'm going to go with an aftermarket kit. Haven't decided which kit yet but either way, I want to plan out where I'm going to get power for the elements. I do have a good understanding of auto electronics and am happy with using relays etc. etc. Question: Where will the best place to get hold of a switched 12v supply that can handel the 4-5A current each seat can draw at max (while heating). This will be my first electrical job in a Porsche and I'm frankly struggling given how Porsche puts a specific loom into each car's options spec, rather than a one size fits all approach I'm used to with other cars. Tap into seat power: Although I have manual seats, the back is still motor drive - so first thought was that I could borrow 12v power here. The wiring is also likely up to the job given that seat motors can draw up to around 20A. BUT the supply here is always on - not switched with ignition - so I'd inevitably leave the heaters on and drain the battery. There is a BOSE module under the drivers seat, so an option for power there, but even less detail/info about about specs here, and it dosn't answer the passenger side question so that's out. Center console: Seems to be a source of switched power in here - but concerned it won't be rated/safe for the current draw - given it will only be designed for accessories and phone charging. Also - as above, how do I get under the carpet to run this neatly from the center console to under the seat? Run wire from the Fuse Box: This is what I want to do really, and use a spare slot on the factory box for a centralised fuse location (I have having fuses just.. hanging around) - but I'm looking for a way to run the 12v neatly back to under the seats and leverage the existing cut out in the carpet to run the wire. I'm good with getting behind the carpet around the fuse box.. and getting the wire to the other footwell - but how do I get to the seats in a neat and tidy fashion? Can't find a guide or info on lifting the carpet on a 987. Perhaps I could tuck under the inside door sills? Your help most appreciated! Kind regards, Rob
