So the black with pink stripe is the light hot lead then and the grey is the tach lead to the coil? Why would one want to have the lights in the tach on all the time? wouldn't a switched hot lead to the dash light circuit be better or is it to help with lense fogging? and I think I read somewhere on the FGF site that I am supposed hook up a small length of tubing from that nipple coming off the bottom of the tach over to the heater box? to stop fogging? Do I need to do that or do most just cap that? or leave it open to breathe in warm engine air? or what? thanks for your help folks.
