[Chevelle-list] Tach

[Mikey]

 Hey Guys,
                  Does anyone have any ideas on wiring a tach ? This is for
a 67' SS the one that's mounted on the left side of the dash. there's a blue
,black,red, brown,grey. I know the blue is for the signal & the black is
ground & grey for light. Does the brown go to the dist. & the red go to ign?
The brown lead is very long.
Thanks
Mikey
