So what wires need to be use on the RS for ignition 2?

H3/1 Pink (Ignition 1 Input/Output)
*H3/2 RED / White (+ 30A Fused Ignition 2/Flex Relay Input 87)
H3/3 Orange (Accessory Output)
H3/4 Violet (Starter Output)
H3/5 Green (Starter Input)
H3/6 Red (+ 30A Fused Ignition Relay Input)
*H3/7 Pink/White (+ Ignition 2 Flex Relay Output)
*H3/8 Pink/Black (87a Of Ignition 2 Flex Relay)
H3/9 RED / Black (+ 30A Fused Accessory/Starter Relay Input)

Is H3/2 ran to a 12v Constant and H3/7 ran to the ignition 2 (green) on the ignition harness? Or is H3/1 split?

From what I am reading, the above line is correct.

I have exactly the same questions as the original poster, except on my 01 Yukon, only thing different is my 2nd ignition wire is white instead of green.

Is it correct to connect both the red and RED / white viper wires to the vehicle red constant?

The real question is how is the 2nd ignition wire supposed to be powered?
a. just connect it to the pink veh wire along with the pink viper wire?
b. power the 2nd ignition wire using the onboard flex relay: connect the pink to pink(veh), the red and RED / white to the red(veh), the green and violet to yellow(veh), and the pink/white to the 2nd ignition wire(veh, green for op, white for me)
c. none of the above.

What exactly triggers the continuity of the flex relay? power at Ignition 1?(pink)

Thanks in advance for any help!

Whoops forgot, what about this wire? does it need to be powered? By the description, does this feed the power to the starter, and to the orange accessory wire?

H3/1 Pink (Ignition 1 Input/Output) - Pink on the ignition harness
H3/2 RED / White (+ 30A Fused Ignition 2/Flex Relay Input 87) -12v Constant (Red on vehicle)
H3/3 Orange (Accessory Output) - Orange on vehicle
H3/4 Violet (Starter Output) - Starter car side
H3/5 Green (Starter Input) - Starter key side
H3/6 Red (+ 30A Fused Ignition Relay Input) - 12v constant (red on vehicle)
H3/7 Pink/White (+ Ignition 2 Flex Relay Output) - 2nd Accessory (White on yours, green on mine)
*H3/8 Pink/Black (87a Of Ignition 2 Flex Relay) - Not used
H3/9 RED / Black (+ 30A Fused Accessory/Starter Relay Input) - 12v constant

Yes H3/9 does need to be hooked up. Powers your accessory wire and starter relay.
