Yes it should do as long as the chassis numbers match up and part numbers match its only under the floor thats changed on the convertable who ever your buying it off should know orvtry before you buy

I have a W208 so it might be slightly different.
Check the following locations.
Under the bonnet main fuse box.
Open drivers or passengers door and look behind the flap on the end of the dash that is hidden when you close the door.
in the boot (unlikely here) under the boot floor is the battery and another fuse box. (mainly for the rear electrics)
Your manual should list the locations. MB manuals tend to be actually useful.

its inside the transmission. you need to pull the pan off trans to get to it. check the wire connection on the trans for corrosion first

The bulb holders are the smaller,usually white, twist locks directly above the large black headlight cover. It's tucked under the cross bar the bonnet catch bolts to. If there is no bulbs in there you will need the orange coated ones. If none of the indicators work check the fuses and the relay as well.

under the passenger seat

w208 PT1 MB part # I recommend using this OEM Fluid ONLY

Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

Not really. Your best bet would be to Ebay the part. Or just bite the soap and take it to the stealership.
