can I have a clear guide for the wiring for paired inj and coil

using FT450 for my V8 Chevy SBC

do I wired all like firing order ?

Firing order = 1-8-4-3-6-5-7-2

pin 8 = 1-6

pin 9 = 4-7

pin 10 = 8-5

pin 11 = 3-2

And injector wired the same way?

For batch fired that is correct - late model cars used a different camshaft that swapped 4&7, to give the firing order 18736542*, but that doesn't affect the batch firing.

Same thing for the injectors, if you're using batch firing.

If you swap to full sequential, just double check the camshaft lifts the valves in the first or second firing order and set the order in the software to suit. Unless otherwise stated, I would assume the 'old' order.
