Engine Install (getting no spark) HELP

[SEVENTY1]

Hey guys I am in need of your expertize. Over the weekend I dropped a 350 sbc in my 71. When it came time to start it up, the motor turns but cant get it to start up. Upon close inspection I noticed that I was not getting any spark. I've got a new distributor cap and coil, and what I noticed on the coil is that I've got the plug that goes from the distributor to coil connected. Right infront of that it shows that there is another connection end that I have nothing connected to it. Is there supposed to be another plug that maybe has current or something that need to plug up to the coil?

Any help is appreciated.

Thanks
