Hi there
Picked up an old tacho at the bug-in on the weekend, and was just curious as to how i should wire it up.
It has 4 wires coming out of it, a red, a black, a green and a white.
Now i assume that black and red would be earth and power, but what are the other two? And where to i hook them up?
I'll put some pics up later, its an interesting old thing! It has "Kmart" on the dial face!:o :P:thumb

white would be backlight, hooked to say speedo light wire

green would be the signal for the tacho, wired to negative side of coil

The guys at KDFwerks had a stall clearing out bits and pieces at the Bug-In show and shine.. It was only $15 so i thought why not?? 😵‍💫

Hi

When you run the wire for the tacho signal, you can then also use it for a kill switch.
