I’m replacing my alternator to one with internal regulator, but got confused when I was going to do the wires to bypass external reg.
My F-2-3-4 at regulator are blue-green-red-black
F Blue goes to #2(F) on alternator
2 Green goes to ....................?
3 Red goes to horn relay
4 Black goes to some kind of condensator(?) mounted next to regulator
It didn’t look the same as I watched on YouTube... But can I just do the bypass F-4 and 2-3?
The #2(F) from alternator is blue and goes to F (blue) on the regulator.
The #1(R) from alternator is purple and goes to.....(GEN light in dash maybe?)

The 1961-63 color codes are different from the later GM colors, so you'll actually need to look at the wiring diagram and not the interwebs.Since you're using the CS130, all you need to do is connect the "S" terminal (sense) to the stud on the horn relay, the "L" terminal (light) to the wire that feeds the GEN light on the dash, and the BATT terminal to the horn relay stud. Done.

I couldn’t get the CS130 to any reasonable price or time here in Sweden, so I got a 63A “standard” alternator. It has the 1(R) and 2(F) connections, and the +.
I tried to look at the wiring diagram in manual but it didn’t look quite the same as my wirings so I lost my self confidence...again🙄 😓
But if I translate from your SC130, the S is F and L is R on my alternator?
And when wiring is done, just let the old regulator be connected in place?
The wires in your regulator serve the same purpose as the ones in this diagram, just the colors are different. You can jumper the connector as indicated in this diagram and just get one of the little conversion harnesses to adapt the plug to your SI alternator. Speedway even sells a kit with the conversion harness and a plug for the alternator connector that has the jumpers already in it. Or, if you just want to run new wires, the #1 terminal on the alternator goes to the GEN light and the #2 goes to the power stud on the horn relay. In any case the old regulator gets trashed.
