RS2 Seats in a 1991 S2 coupe (3b) and wiring

My 900 was running the Td04

And 8 injectors

I know you dont need a Gt30 in a Aero but it is nice.
Friend of mine was running a 28Rs but he didnt get enough torque steer so hes fitting a 30 instead

Well.. things progress in timely fashion (slowly that is..)

I've broken into prostys S2 Avant and checked the wiring of the seat-warmers..

Behind the dash-switches i found the following:

Left-hand-side switch (in our case, the driver-side):
1. blue/black
2. black/yellow
3. black/white
4. red/white + red/white (goes to the right-hand-side switch)
5. black/blue
6. brown + brown (goes to the right-hand-side switch)

Right-hand-side switch:
1. blue/black
2. blue/yellow
3. blue/white
4. red/white
5. blue/black
6. brown

Under the seat I found these:

Left-hand-seat (in our case, the driver-side):
1. blue/brown (connects to 2)
2. blue/brown (connects to 1)
3. black/brown
4. brown
5. black/white
6. black/yellow

Right-hand-side:
1. blue/brown (connects to 2)
2. blue/brown (connects to 1)
3. brown/yellow
4. brown
5. blue/white
6. blue/yellow

Where does one find the relay for the seatwarmers/what fuse am I looking for? (my german ain't that great) (;

The harness isn't rs2 specific I think. It's the same as in other b3/b4 cars with electric seats.

You could most probably use the usual b3/b4 seat heater harness from any car and just figure out what's needed for the electric adjustments. Finding a seat heater harness can't be very hard in Sweden.

All cars originally sold here have the heaters, so why not there?
