Yea power window question

[mygmctruck1]

I have checked out many of the power window threads untill my eyes crossed.
My truck a K1500 68 GMC

My questions ?

I have the A1 power window set up , not yet installed . No wiring harness yet .

So I have an AAW harness with a power window circuit and feed wire , 30-40 amp , I believe. Do I still need relays for motors ? If so where did you all mount them ?
I don’t not see a place inside the door ?

Who’s wiring harness and switch’s kit did you use ? I am leaning towards the old style lever chrome one’s
Last question , what did you used for a loom between door and cab ? I don’t mind drilling a hole to pass the wires thru but don’t want to start cutting Large holes in the door or kick panel .. Just got truck back from a fresh restoration .
I would really prefer plug and play as I hate wiring .

Ya know , I did hugh commercial mechanical Systems , steam & hot water boilers up to 10 million btu’s , chillers ,Process water . Etc and I know my stuff . But when it comes to automotive wiring , I am a total dunce !

If you have pic’s I would love that.
