wiring the ignition switch - with coyote, are both brown wires needed for ACC?

[toadster]

n00b question... wiring up my ignition switch, red, orange and blue are easy...

but the brown ACC and Alternator-IGN I have the question...

the RF Manual (Rev W) shows

I'm installing the Gen3 Coyote with the M-8600-M50BALT Alternator Kit

unsure if the alternator is a 1-wire or 3-wire?
my assumption is 1-wire, but figured I'd check with the forums before I cover it up
