Look in electric diagrams
So you are not going to use the Fuel injection computer, right?
And you will be using a vacuum advance distributor not a TFI system which needs a computer, right?
Then there really are not many wiring changes outside of moving them out of the way.
Alternator wiring should be the same, assuming external voltage regulator and an alternator that uses an external voltage regulator on the '84 engine.
If you want to use a newer alternator then wiring changes are specific to the new alternator not the motor swap.
Alternators with external regulators are call 1G(1st generation)
2G have internal regulators as do 3G alternators
Google: 1G to 2G conversion
or 1G to 3G
There are only 3 other wires used on the engine.
Coolant temp sender, 1 wire
Oil Pressure sender, 1 wire.
Key on voltage to coil/ignition module, 1 wire
Tach wire, if needed, goes to coil "-"
If you have AC that adds 1 more wire, to compressor
Starter relay is not on the engine so its wiring shouldn't change
If you use an electrically heated choke for the carb then you will need to add that wire
