EEC IV connector is a very simple connector Dangling from the end of some wires most likely. There will also most likely be a single wire with a single female spade connection on the end of it. You will need a factory manual to decipher codes. Either a fancy code reader that counts the pulses for you, one that has a light that lets you count the pulses, or a simple analog volt/ohm meter that you can hook up to count pulses and convert these pulses into codes.
An OBD II code reader will NOT work on this vehicle.
At least you have the throttle body fuel injection. This is a very good system that Ford used for quite a while. My Dad's '84 LTD (small car) had a TBI EEC IV system and it was a mid year introduction from the earlier two barrel carb. Worked like a charm for the entire life of the car. They just added a high pressure fuel pump under the floor. Never did like having that pump exposed to road rash, etc, but it lasted nearly 300K mi.
I am basing the above on my familiarity with the EEC IV system in my '91 Ranger and one or two slightly later systems I have messed with. Its all basically the same, but Ford may have changed some of the details.
