Power Window Wiring

[dunnm]

So the PO changed the doors on my '71 to a later vintage (80's im guessing, see PIC) and tried to wire in power windows. There was no existing wiring so I'm assuming the car originally had manual windows. The only wiring I'm able to locate is three wires that run from the DDPW to the PDPW (all 3 are brown). None of my switches work but I confirmed that both motors are functional. I do have 12 volts at Fuse 3 but not at the window switch so something is amiss with the wiring in between. My question is from fuse 3, where does that wire run and is there a relay involved somewhere? How many wires should go from trunk into the drivers door to the switch? I'm trying to cross reference the diagram on this site but without accurate wire colors I have no idea whats what. (also confused that Fuse Box I is in the diagram with the 3 fuses, my car has the 10+8 fuse setup). Any guidance greatly appreciated.

In my 85, the drivers side window has 1 red wire with a jumper from the top pin to one of the bottom pins, 1 blue, 1 blue black and 1 brown. The passenger side has 1 red with a jumper to the lower pin, 1 red white, 1 red black and one brown. The passenger side door has 1 red black, 1 blue, 1 blue black, 1 red white and 1 brown.

Yeah I have that wiring (colors are inaccurate though. Trying to figure out the wiring setup/scheme from fuse to door.
