Where does the wire hook up to. The ECU or to something else.

Your tachometer should be controlling the light, the wire should plug into the tachometer somewhere. Did it come with instructions?

i remember some one was saying is the little blue wire next to your fuse box in the engine bay, its the wire they use to run test on the engines or something, and it will work of a shift light, later,

Please let me know too--I want to add a shift light at some point later.
