Study your diagram again.
Hint: Bipolar Parallel Connections
Blue/Wht and Red/Wht to A+(A1)
Blue and Red to A- (A2)
etc
The easiest way is to hold a pair of wires together and turn the stepper - if it’s hard to turn, that’s a pair, if not, try another pairing.
It doesn’t matter which wire goes where, as long as they are a matching pair connected to a matching A or B of ports.
425oz steppers are going to stretch a TinyG - keep an eye on the temperatures. Be prepared to purchase external drivers - they are cheap enough, nowadays.
