Red face Possibly a stupid tach question

Where do I hook up the tach wire on my 77 c10. I know its on the distributor but where exactly? do I need to remove the top or is there a port where it plugs in?
Thanks guys

There is a terminal on the back near the firewall, no need to remove anything to hook up a tachometer.
