Hi Is it possible to wire up a cheap neg earth tacho to my pos earth Devon
I don?t want to make this a permanent addition
The tacho has 5 wires
Yellow to light
Black to battery
Green to coil
White to ignition switch
Red to pos batttery
If I wire it exactly as shown will it work the thing that interests me is the connection to the coil this being a pos earth van
Thanks Tom
