Need a little clarification on full sequential injection

Edit: I have a ms2 v3.0 going to run ms extra
So i understand where to jump the u2 chip and remove R21,C20,C21,R22,R23,Y1,C24,C25 from the clock circuit.
Where I am confuse is that it says that pin 4 and 5 can now be used for injector 3 and 4 but then it tells me where the 4 injector channels are at.
Do i need to run my injector wires to these 4 channels? or can i just run from the normal injector bank 1 and 2, and pin 4 and pin 5.
Is there any additional hardware that need to be installed?
and yes i did look for answers lol non were present.

I was planning to use the Jbperf board for full sequential.
4-Channel Ignition/Injection Driver Board
4-Channel Ignition/Injection Driver Board

Sequential Injection Code for MS2
Good board, ran my low-z injectors off the peak and hold board.
You do have that board, right? Right? Because if I'm understanding you correctly - no, you can not run your injectors directly off the megasquirt board by doing that mod without having the injector driver board.

The circuit for injectors is pretty darn easy, if you have a clear proto area you could easily add all four drivers in there.
this picture shows how I add two extra drivers on a DIYPNP:

You'd have to build all four on a v3.0 Ms2.
