Radiator Fan wiring, Gen3 Coyote with A/C & Flex-a-Lite fan

[toadster]

working on the radiator fan wiring, still waiting on my Coyote ECU/PDB setup from Forte...

overview of parts: (think FFR Gen3 coupe with A/C)
RF harness
Gen3 Coyote ECU
A/C kit with Trinary Switch
Flex-a-Lite Wave LoBoy Puller 16" fan

there are 3 wires in the RF harness
Black: Radiator Ground
Blue: Cooling Fan
Dark Green: Thermo Switch

2 wires on the Flex-A-Lite Flex-Wave LoBoy Puller Electric Fan
Red (+) on the puller fan
and Black (-)

I'm a bit conflicted as to what controls the fan at this point
- Coyote ECU, ORANGE wire to fan positive terminal which I assume is the BLUE wire
the Fan Black(-) goes to ground on the RF harness

from the instructions below, does the red/blue trinary switch go to the dark green thermostatic wire on the harness?
also, it shows the BLUE wire in the A/C harness going to the fan with the engine control wire, is this spliced with the Orange ECU wire?
