2 eletrical plugins on firewall

[tiptopss]

hey hows it going, i am wondering if anybody knows what the 2 eletrical plugins are that are on the firewall of my 85 mustang gt. its just a bracket mounted on the firewall right behind the passenger side valve cover, and has 2 plugins on it but it also has those plastic tubes coming out of it. reason i ask is because when i tried to start my car tonight i just had a loud clicking sound coming out of there, and now no way will my engine turn over now, it just keeps clicking, so i needed to know what that is or whats in behind it cause i think its causeing my car not to start. thanks

That should be the TAB (Thermactor Air Bypass) and TAD (Thermactor Air Diverter) solenoids.
