Very simple and straight forward. First, disconnect the battery negative terminal…second, select the number of cylinders on the back of the tachometer itself. My tachometer has 4 wires attached to it…red - power from the ignition when turned on (red wire from the ignition block) , black - earth or battery negative , white - dashboard lights (connected mine to the cigarette lighter led wire live) , green - rpm signal (on mr2 this is the IG- screw directly behind the rpm clock on the dash cluster pod).

I used the propper little splicing connectors to join the wires together because they cost pennies and do a better, safer job than twisting wires together.
