I bought a factory tach from a DS650 Baja and i'm in the process of installing it on my 01 DS650(non-baja). Does anyone know what wires go where? There are three.

Red
Black
Green

Help!!!

 

i think
red=power
black=ground
green=goes to coil wire

 

Thanks for the reply. After looking at it for a minute, i figured it out. Cut the hole in the dash, mounted the tach, and wired in about 30 min. Looks great and actually works!!! Kinda hard to see at low revs, but i knew it would be. I only need it for consistant launches and to know where to shift(i can see 7-8500 easily).
