Can some one please confirm this because i dont want to blow the tacho up....
Thanks Jason

Hi n_dorphin, this was discussed recently. Using the search box I found Tacho Connections, which should answer your questions. Or maybe just confuse

this is confusing. Hope i can do it.

yeah i just bought one....but me mate installs that kinda stuff for me...
i watch and learn...its the only way...still workin out where i should mount it....ne suggestions??

Mate, it's easy. If you know which one goes to 12v, one to earth and the other to the negative side of the coil..then it's easy as...

You can't really blow anything up. Keep away from the high tension lead, if you are wiring up while the engine is running.

ok tried all the ideas, One made wires smoke (+ coil and ign) and the other (using the neg of coil and dizzy) wouldnt start.
Help please

n_dorphin, it makes a huge difference ... is yours a factory 1200 tacho, or is it an aftermarket unit?

If it's a factory unit, go to the other discussion and click the link for the wiring diagram.
