791xv starter wire connection

i have a quick question on hooking up the 791xv remote start,

for the heavy guage wire the purple and green wire both connects to the starter wire,

the purple is on the starter side

the green is on the key side

so does this mean i just cut the starter wire in half?  and then tap the  purple to the starter side and the green to the key side?

OR

do am i NOT suppose to cut it and just T tap it to side its suppose to be on?

thanks...

the benefit is the antigrind feature, this way when the car is remote started, you cant grind the starter by turning the key too far.
