Install Seat Wiring
Layout your new wiring as you desire, i layed the cables with the current looms within the car on both the driver's and passengers side and secured within the retaining clips.
Have a seat ready next to the drivers door and reconnect the cut blue/black connector to the wires you have placed within your fuse box either via soldering or joining blocks.
Next from your connector there is a pink/white wire, this needs to be connected to a CAN line within the car, the best place to find this CAN line is the fuse box under the steering wheel, there is a bunched up loom on a connector to the right of this fuse box, splice the Pink/White wire and attach via your preffered method
Now its the moment of truth, plug the blue/black connector into the under side of the seat blue/black connector
Reconnect your car battery
Turn on the ignition and test, hopefully the electric seats move forwards etc...
If so test the passenger side seat with the passenger side wires and connector
Hopefully you have working electric seats.
