Probably not a difficult one but I retrieved this from somewhere in the interior of my T350 and I'll be blowed if I can work out where it comes from. And, just to pre-empt the comedians, you're not identifying the tap, washbasin or tiles.
Yes thats correct. Down where your right foot is. Mine came away to, if it wont restick you could try wedging it with a bit of rubber or something against the pedal box.
Yep, ECU cover in drivers footwell. You may ned to cut this down to make it fit correctly and put a couple of self tappers in it as well. I have done this on all 3 of my TVr's and it has worked fine.
