If you have a new updated alternator wiring harness all these wires should be in place.
If you have a new original style engine wiring harness for a generator there was:

A small dark blue wire from the small field terminal on the generator to the voltage regulator should be deleted.
A small black wire (ground) from the generator case to the voltage regulator mounting screw should be deleted.
A red wire from the voltage regulator to the horn relay should be deleted.
A large black wire (12 gauge) from the large armature terminal on the generator to the voltage regulator can be moved to where the red wire was on the horn relay then to the BAT terminal on the new 10SI alternator.
Another large black wire (12 gauge) from the battery positive post cable to the voltage regulator can be connected to the same terminal on the horn relay or to the BAT terminal on the alternator.
A small brown wire from the dash tell-tale light to the large armature terminal on the generator should be connected to the #1 terminal of the two-wire plug for the new 10SI alternator.
Run a jumper wire (16 gauge or large) from the #2 terminal of the two-wire plug to the BAT terminal of the new 10SI alternator.
A small red wire from the under-dash bus connection to the voltage regulator should be connected to the same terminal on the horn relay or BAT terminal of the new 10SI alternator.

Remove and delete the voltage regulator. Done
