If it is the 2 5/8" Pro series gauge then use these instructions:

"Matthew,

Green wire connects to “S” terminal and to negative side of coil. If there is an aftermarket tacho pick up wire, connect to this wire instead of negative side of coil.

Black wire to “G” terminal and to earth.

Red wire to “I” terminal and to ignition switch.

White wire connects to the thick black wire from lighting globe assembly and then to dash lights.

Regards,

Bob Forrest
Speco Thomas"


Cheers
Matt
