OK Jupiter, They are located on the crossmember running under the front seats. You will have to remove the front seats and unplug the sensor connectors, having done this, you will have to lift the carpet. The trims strips along the door holding the carpet will need to be removed. The carpet cannot be lifted without removing all the trims and fittings so I found it easier to cut the carpet from under the seats by the handbrake housing across to the bottom of the piller by the seatbelt anchourage. Peel the carpet back from the cut and expose the crossmember. It seems that the Orange ones (The ones I have for sale) are located nearer the front of the car (down by the front side of the seat in the corner of the floor pan)and the green ones that are in mine are behind the seat bolted onto the crossmember.
