hey mate, ive just bought a nismo 300km/h speedo for my 34 gtt, but im having problems with it. its plug and play, has the same 3 plugs from the standard and should work no worries. but when i plug it in, all i get is the seat belt and engine light illuminated even when the key is not turned on. the dials do not work at all, no speed or revs. have you heard of anything like this before mate? is there much that can go wrong with them, or am i better off sending back to supplier?
thanks champ
