87 chevy doors on my 74, power window n locks questions

[frog210]

hey guys i have a few questions
I just got my hands on 2 87 chevy doors power windows and locks($100)
im going to be putting them on my 74 chevy
i hav heard that i will need to run a 10gauge wire from the battery to a 30a fuse then to the harness?
ive been searching for like 3 days
Is their a way to try the window motor and locks without the wiring harness
(i got to go to find one), and without taking the motor out of the door?

Could i just put the door infront of my truck run a 10g wire from the battery with a 30a fuse?

Or is there a how to take the motor and solenoid out?
ive been searching here but i might not have been wording it right
If i do take it out what would be the best way to leave the window in their when i take the motor out? tape wire
