I'm removing my 305 throttle body engine. im trying to remove the main plugs off the driver side firewall and im having trouble getting them off. i believe its just 33 years of florida summers melting everything together. i popped the clips on the outside plug and the cover came off but it didnt unplug. am i missing a secret way to do this?

 

There is a small 6 or 7 mm bolt in-between those two harnesses. Hard to see.

 

thank you! i totally didnt see that.
