Since no one seems to have provided all the right answers, see here:

This is specifically for MGA, but should be the same for the MG TF.

If you want to install a negative earth radio in a positive earth car 
(or vice versa), do NOT atttempt to isolate the case form the dash 
panel.  That might work for a while, but there are multiple ways to 
accidentally short the case to the dash and blow a fuse or burn 
wires.  For the proper way to do it see here:
