What are you planning on using to replace the EEC system? I would recommend keeping the egr unless you are racing this truck. You can back date it to keep it working, but for highway cruise, it helps with efficiency a bit. As for spark control, you could backdate it to duraspark, or some type of aftermarket ignition. Then there is the fuel metering... Now if you are calling the duraspark the EEC, then the two plugs are the power supply and the wiring to the distributor. There are 2 power levels, one for starting, the other for regular operation. Unfortunately, to me, you info is a shade weak, so more on what you plan and what you have would be helpful.
A little patience too, please, we aren't all just sitting at the computer waiting for someone to ask a question, we still have other things to do...

It's been a while, but if I recall correctly, the white wire is the 12 volt, and the other is the regular run, which is about 9 volt I think, then the other plug goes to the distributor.I doubt that it will just plug in, rather, you will have to do some wiring work.

I won't be able to help any more than that, I worked my 92, but not a the 87-91's, so can't say much without investigating it myself...

If they were to the eec system, you don't need to worry about them, just be sure none of the guages run through them, and do whatever you want with them. I did a 460 injected to a Cummins diesel swap, and tapped into a few for the guages and ignition, and the rest collect dust and crud... I unplugged it, and unfortunately, the big plug is still there, as not much else I could do short of hacking it all off... I spliced into the harness on the back side of the plug, and did away with the harness on the engine. You could clip your wiring back, and leave only the guage wiring, but personally, I would take the harness, tuck the unused wires into a loop or such, and just tie them up, just in case you should decide to go back.
