e34 seats in e28

[Emil.ahnberg]

Hello, i have e34 leather seats in the front and back. They fit quite good but thats not the probkem. I want heated seats. The wiring on the driver seat have no cables(someone cut them of) but i have the whole wiring harness to solder. But i wonder how im gonna connect it to the e28 wiring? theres 4 cables from the e34 and 3 cables from the floor. Have someone fixed it so that you get heat in your seats?? Ive tried to look after power from the buttons etc. But cant seem to find the right on etc.

You will want to run a power wire up to the power block on the firewall, there is a pin dedicated for seat heating.
drivers side, left of the steering column.

Power wire from the power block to the seats or from the button? i belive tthe wiring from the buttons is intact, but its the connector from the seat to the harness from the floor.
