    When fitting the Cabrio module to the 230 the old instructions included fitting in the rear fuse box as well as the driver’s side sill box. Now they only come with the driver’s side only instructions.

    One thing is for sure, that is it is a pig to get to the drivers sill box. The inner sill cover has to be pulled up and off, no matter if fitted in the front or rear.

    It is dead simple to fit it in the rear box.

    Sill cover, lift up and off.

    Remove 4 screws from top of B pillar and remove the chrome trim corner piece.
    Pull the door rubber seal back down to floor level.
    Open rear box and prise off the front panel from the top, only hook in bottom.
    Remove 1 screw from side panel seen in the front of the box.
    With a thin screwdriver, prise up and off the last sill clip to release the bottom corner of the side panel.

    The side panel on early cars is held at the top by 2 long plastic clips, do not just pull the panel at the top inwards or the plastic clips will break. Just ease the panel inwards and look in where the 2 clips can be seen and use a long flat bladed screwdriver to ease the clips out of the metal side. Later cars have reinforced clips, with this just lever the panel inwards. On early cars there are 2 hooks in the rear of the panel that hook into the rear panel. Gently lift the side panel from the bottom and upwards, and it comes out. Later cars have only 1 hook at the top, just pull the bottom forward and lift from the bottom and its out.

    The CAN connector is the long one towards the outside of the car, push a thin screwdriver down in the centre to release the holding clip and it slides off. You can now work with ease.

    I always fit a fuse holder to any additions in the electrics. Please lease the fuse out till the CAN plugs are connected. Fit the black ground wire to the ground bolt on the wheel arch, the only one with all the brown wires connected. Join the red lead to the red lead with the green stripe with the crimping block provided. You can see the red wire with green tracer here.

    The CAN plug will only work on the 4th or 5th CAN connector from the right, start with the 4th .Release the clamp holding the plugs in as per instructions, and pull the plug out, push the module plug in and connect the plug you have taken out to the module lead with socket.

    Plug the fuse in and press the phone hang up button on steering wheel, if all good you will hear a bleep, if nothing, remove fuse wait 2 minutes and replace and press hang up button again, if it bleeps all is good, if nothing remove fuse and move the CAN connectors to number 5 and it should work.
    I found that once this is installed all memory functions like the seats now give a bleep. The main thing to remember is, the fuse must be taken out when changing the CAN plugs, or it will not work.

    The nice thing about putting the module in the rear box is, there is no bending down as you do it all by leaning over the side of the car.
    When my sill was off I put it on my polishing buff and made it like new, stainless sill covers fitted from 06-06 onwards
