2 reds to the larger connection "B"

black to the smaller one "S" that you removed (if you cant remember which ones you removed then look for the shiney bits of thread on the solenoid studs)

all the connections go to the solenoid you will have a positive in "B"(battery wire) a ground out "M"(which could be a link wire to the motor casing itself) and a positive 'trigger' wire from your ignition "S".

the 'trigger' wire is a low power feed from your ignition switch, this energises the solenoid, which allows the power from the battery to be dumped into the starter motor itself, giving sufficient power to engage and spin the motor.

the wire 'going off to the alternator' is actually a 'return' feed from the alternator supplying 13.8v @ 80+amps... its connected to the same connection "B" as its an easy way back to the battery instead of running a separate cable back through the engine bay
