Need some help from someone with electrical skills!
The tach is already wired up and working. Now I'd like to get the lighting circuit working so the tach lights up when I turn on the nav lights. I was thinking this would be as easy as jumping a lead from the nav light switch over to the tach (and maybe it is that simple) but the TACH INSTRUCTIONS aren't very clear (see #8)...especially since I don't have an "instrument lighting circuit."
Even tho' it seems like it should be simple, I just can't seem to figure this out. For example, if you zoom in on the diagram it appears that there are 2 blade terminals for the tach light, but the description on the diagram is exactly the same for both (???).
Anyway, all I'm trying to do is get the tach to light up when the nav lights are on, so any help would be greatly appreciated!
