ok, so I finally had the time to do the wiring on my seats...first I opened the box....
and unravelled the mess...
I located the plugs that I needed and started to unpick the tape...I do not recommend this as it is a bugger to do...there is no way you would get these wires out of a scrap car.. the only way is if the loom is in front of you.
after a couple of hours I ended up with this...
on the passenger seat there are 7 wires coloured as follows...
thick brown... this is an earth.
red and yellow...this goes to the fuse box...fuse number 37 which should be a 30 amp.
red and black...this joins up with the red and black on the drivers seat and then both go to the fuse box...fuse number 34 which should be a 15 amp.
blue and purple...this wire goes to the drivers seat and joins to the blue and purple on the seat connector.
white...this goes to the central electric control module..if you remove the lower dash panel on the drivers side and look above the accelerator pedal, you wil see 3 big plugs. 1 is black, 1 is white with a black locking clip and the other is white with a sandy coloured locking clip. you need the white with the black clip which looks like this...
I you look at the end where the wires go in, there are 2 tabs which, when moved, hold in the inner part of the plug...
this inner part then slides apart...
the white wire goes into the 4th small hole from the end...
there are 2 remaining wires , blue/yellow and a blue/white. The blue/yellow joins to the blue/yellow on the drivers seat then, along with the blue/white, go to the climate control unit in the dash... on the back of this there are 3 plugs marked A,B and C. you need plug A which looks like this...
the next picture shows the position of these 2 wires when fitted, blue/white to the outside and blue/yellow to the inner...
the only problem I can foresee if you are making your own loom is the connectors... the blue/white and blue/yellow for example...
the white wire also has this connector on the end...maybe maplins or the like sell these??....the connectors on the seats can just be cut off and each wire can be fitted with spade or bullet connectors.
The 4 wires from the drivers seat should be connected as follows...
thick brown...this is an earth.
blue/purple...should be joined to the blue/purple coming from the passenger side seat.
black/red...this should be joined to the black/red coming from the passenger seat then both go to fuse number 34 on the fuse box.
blue/yellow...this joins to the blue/yellow that comes from the passenger seat and then goes to the climate control unit in the dash.
all that is left to do is connect up to vcds...go to central electrics and find 'seat heating enabled'...check the box and hey presto...warm arse!!!
this was all done on a 61 plate (2011) scirocco gt tdi blue tech so if any wires are different then ??????? and if your car sets on fire its not my fault..
also, if the remaining loom is of any use to anyone, its in the for sale section for any reasonable offer.
hope this helps.
