Theres a tan w/ a yellow striped wire behind your gauge cluster, thats your tach signal wire, you splice into that for the dist/tach wire, and everything else is easy, find a place to hook the ground wire, hook the pos. wire into the fusebox. Make sure the tach your using works with a distributorless system, i found that out after i installed an old tach, and had to take it out since its for an engine with a dist.
Good luck
