late 80s 5.0 help needed

Please list the numeric values for the codes and I will give you the Mustang specific code definitions and fixes. The codes need to be sorted out first and then use the code data to get pointed in the right direction.

I am trying to get ahold of an OBD scanner so I can make sure, but if I am counting the flashes correctly, the codes are, and in this order, 81, 82, 85, 84.
The light I am reading is not an actual check engine light as the car does not have one. It is just a bulb and the light sort of double flashes-making the counting a bit harder. I have a video of it-is it possible to upload that to this site so I can get a second opinion.
 
Air injection solenoids, charcoal canister and code 84 is EGR related, which I assume is also deleted?

None of those codes really affect how the car runs. Code 84 disabled the EGR function in the ECU.

Resistors should be able to make those go away. You just need to know the correct values
