ported and polished throttle body

[iziballs1]

hi i recently got a one done and sent to me, its for a westcoast but when i looked at the one which is already fitted, it looks plastic, are there to types?
also on the new one theres a 2 prong plug at the bottom on mine its not there.
any ideas?

cheers.

Sounds like its for the wrong model matey, could be from a mk2 if yours is a mk1 or vice versa.
