When Wellsy fitted his own he couldn't seem to find a defined DIY guide on how to fit it and encountered problems along the way, so after many days of frustration he eventually figured it out trawling through the many 'how do I fit my heated seat loom?' threads.
Removing the front seats:
- disconnect the battery for 30mins so the airbags don't go off
- take off the trims that cover the runners 2 x screws
- undo the 2 x bolts at the base of the seat, once undone the seats will run out of their runners
- disconnect the airbag cables
Removing the centre vents (standard Golf):
- prise out the actual vents and not the frame with a metal ruler
- undo the 2 x screws (top corners)
Removing the centre vents (Bora or R32):

Removing lower dash (under steering column):

Installing the heated switches:
- feed the 2 x larger plugs (rectangular & black) on the Kufatec loom from the steering column area to up and behind the centre vent area

- remove the 2 x blank switches within the centre vent frame

- install the 2 x heated seat switches in their place

- plug the 2 x larger plugs on the Kufatec loom to the switches - DO NOT REINSTALL CENTRE VENTS YET....50/50 chance of having the plugs the correct way round as they are not labelled L and R

Wiring up the Kufatec loom:
- wire 'label masse-' (earth) connect under steering column (round end connector attached)
- wire 'label zondungsplus S5' (switch live) connect to 75x on relay board but you will need to add a round end connector to the wire
- wire 'label schraubklemme KL30' (permanent live) connect to 30 on relay board (round end connector attached) - this is the loose wire

- wire 'label sicherung 44 dauerplus' (fuse 44) connect to rear of the empty fuse slot 44 - you will need to slide the plastic purple locking strip as highlighted in the second picture below
- wire 'label schraubklemme KL30' (permanent live) now connect the other end to fuse slot 44 - this is referring to the loose wire again
- install 20amp fuse to fuse slot 44


- wire 'label beleuchtung PIN17 light shalter' (light circuit) connect to the grey/black wire behind the light switch - to remove the light switch turn to side lights whilst pushing in and the unit will come away
Connecting the seats to the Kufatec loom:
- feed the remainder of the loom under the centre console/tunnel towards the seats
- slacken off the 4 x screws holding the centre console/tunnel in place (2 x near pedals & 2 x gear lever - either side)
- feed the 2 x smaller black/purple plugs under the floor carpet under the centre console/tunnel out to each seat
- plug into seats and refit seats
Testing:
- reconnect battery
- switch the engine on
- turn 1 x heated seat switch on and see which seat heats up - if you're lucky, the correct seat will heat up....if not, you need to swap switches around (HENCE I TOLD YOU NOT TO REINSTALL THE CENTRE VENTS)
Finally.....put everything back together!
