hi, i have just fitted my rev counter on my k10, with the red to positive battery and the black to the negative battery and the green wire to the coil, its works perfectly aswell!! i just needed to know about the wire that goes into the sidelights because this is still disconnected and i want it to come on with my sidelights. i have looked under the steering wheel and there is millions of wires all tied together.!! where have other people wire the tacho lights to? any easier places? thanks adam
