I've watched countless videos, read as much I can, and it's either I fully get it or I'm too dumb to understand. I'm looking for reassurance / direction. 
 
I have an EVGA 850w G2 PSU and I would like to try my hand at making my own sleeved cables for it (not sleeving the OEM cables). I want to start easy and do the EPS and PCIE cables first before I do the 24pin.
 
I know you're supposed to make your own pinout chart, but for the sake of me understanding I'll refer to the pinout diagram that's been posted online.

In said diagram, pins 1-3 are 12v and on the actual PCIE cable I have it has 8 cables coming out of the PSU side--one from each terminal (easy), but when it gets the to GPU side, pins 1 and 5 have double wires.
 
Question 1: I plan on buying my supplies from Mod-One and use their 16awg wire. Do I need to double up on those pins or can I go one to one?
 
Question 2: When running the wires to the GPU side connector, is it a mirror image of itself? e.g. does the 12v wires on the GPU side go into pin 4, 3, 2?
 
Question 3: When reading these diagrams, is the illustration showing the connector as it would be plugged into the PSU (pins tips away from you)? Or pin tips pointing at you?

This one looks pretty straight forward. The top row will be the 12v on both the PSU side and MOBO side? For full disclosure, I have an ASUS Prime X470-PRO motherboard. Looking at the MOBO pinout, the top row on the MOBO are all 12v. And again, if I use a 16awg wire, do I need to double up on the pins at the MOBO side that are doubled?
 
I apologize if my questions are common sense. I tried searching for these, but couldn't find an exact answer.

Thanks for the reply, yes the fear of frying something is real! But what if I wanted to go from scratch and make my own cables like many do?

Okay, I took a spare PCIE cable, labeled and removed pins from the GPU side connector and what I found was that pin 1 and 5 have a capacitor? Well, something attached to them. Hence the down wires on those. Photo below:
 

 
If going in the custom wiring route, do I need this?
 
EDIT: It's worth noting EVGA themselves sell individually sleeved cable sets for the G2 that don't have these caps. CableMod also has kits without caps for the G2. I'm a bit confused as to what my course of action is.

The in-line capacitors are supposed to be for voltage '' suppression that can adversely affect the voltage regulation circuitry in the recieving component, if bad enough.
 
Ripple suppression means 'cleaner' and more stable voltage..Most all PSUs don't have them in-line because ripple suppression/filtering is normally done well enough internally.
 
I guess Super Flower, that is the OEM of that EVGA unit, felt the capacitors were necessary, maybe due to cheaping out on the PSU internals or maybe as extra added quality assurance, don't know..People normally just leave them out when sleeving/re-wiring and report no problems..You can search that and find lots of hits.
 
is the best source for PSU reviews, testing and info (in my opinion).

Thanks, I've been looking around all day and now have a much better understanding and confidence going forward. Tearing down one of the PCIe cables helped a lot too.

Will do! Cables are the only thing holding me back.
