Help needed fitting heated seats

[Jimmy Filth]

Ok, so I've got the wiring loom from kufatec, the relays and the heated leather seats.  I've also taken almost all of the trim off of the dash.

The looms have the plugs to go into the relays under the chairs, then a plug to go into the switch, then a single pin brown plug (that must be the earth) a black single pin plug with schwarz (black) written on it and a black single pin plug with beleuchtung (illumination) written on it.

There is a circular brown connector in the bottom right of the dash that I've been told is the earth for anything in the car, there is then a collection of about 6 plug units, each capable of taking 6 or 8 single pin plugs.  These are various colours.  One of which is blue, one is green.  There are also grey and yellow ones but as far as I'm aware these are of no use to me.

I have also been told that the blue one is for illumination and the green one is for the ignition live.

So I've plugged the brown plug into the circular brown connection at the bottom right of the dash, then the schwarz plug into the green and the beleuchtung into the blue. 

Do I now need to add an extra fuse to the fuse box, or should it work right off?  Car electrics are totally foreign to me and I don't want to wire this up wrong and break anything.

Here's a VW pic of the loom, I've added the colours in just to assist with where I've plugged things.  The loom I have is slightly different in that it is a single piece from the switch to the relays.

black plug into the black or green jumper block, illumination into the grey jumper block, earth to the big round earth block. simples

Cheers.  Will I need a relay for the fuse box too??

[Jimmy Filth]

ok, so now the switch illuminates, but the seats don't seem to be warming up...

Nice one mentioning that site. Some interesting options there. I'm thinking of retro fitting heated seats to my porsche seats.  just need to find some elements. Or can the eBay type work with the Vw stuff?

[Jimmy Filth]

I wouldn't be able to help you there, but I would expect it would.  Give strictly dubs a shout and ask their opinion.

There must be a way to get the elements to work with the VW wiring loom, my guess would be that you would have to cut the seat relays apart and do some wiring yourself, but that way must make it easier than having to do it at the fusebox.  Would look tidier too.

Once I have fitted the seats I might make a how to as I couldn't find one anywhere.  Tht would be for VW seats though.

do you hear the relays under the seats click when you fiddle with the knobs? (you do have the relays under the seats right)

aftermarket elements wont work directly with the vw system, as the vw pads have a thermistor in them which detects how hot the pads are and so allows the knob to regulate the temperature.  if you can find a vw or compatible thermistor then you're all set. if not the other option is to add a resistor of the right rating, this will get the pads workign but there will be no regulation, so they'll only heat up to 1 temperature.

and tbh if you do that you may as well just wire it up with the on/off switch which comes with the pads

Everything I've got is VW, from the seats, to the elements to the switch in the dash.

[Jimmy Filth]

I take it from the fact that the light in the dash switch comes on then there is a current running through and therefore all the fuses and such are in order...

when MJ at MJ Interiors retrimmed my recaros, i did away with the standard VW crap, because it is just that - crap. the heated elements on a mk 3 as standard are wires and these eventually either burn out or burn right through the leather (MJs words not mine)

so he used Carbon fibre elements in mine and iv got it all running with the original switch on the dash, i cant remember the name of the comapny of the elements but they were about 150 quid i think and they were a german made item.

all the new top end cars have carbon elements as its miles better technology. so yeah id say u can use what u like if your savvy
