Passenger side plug is a tap for a tach signal-don't worry about it.
Drivers side plugs...the round one with 1 wire is a knock sensor plug. The knock sensor should be on the block, near the starter. See if it plugged in. If it is, that plug is redundant(don't worry about it.) Although, if it wasn't plugged in, your service light would be on.
Can't think of what the square plug is for..possibly a/c?
The corroded wire looks like it is going to the coolant sensor. If your guage is reading OK, don't worry about it. Otherwise, get a new pigtail from GM.
gtk i right on the knock sensor and the coolant temp. and as far as the white one i dont know what it for but for what its worth my 87 had a/c and all that but that white plug wasnt used in my van...ever...Its all crusty and taped up and stuffed into the split loom...looks like a factory job too...
