ok, i'm an idiot....aftermarket tach question

[88_GT_5_oh]

i have a sunpro tach that i intalled during the winter and i ran the black (ground wire) and the green wire into the engine compartment, but i didn't hook them up cause i didn't know where i wanted to route them yet and now i seem to have missplaced the instructions. where do i hook this green wire into?

man i feel like an idiot

negative side of the coil.

is that the green wire on the coil?

the green does to the coil like said... or the MSD box if you have one. black you can ground anywhere.
