in the picture below what exactly do I do with the black wire and red wire, (The black wire was connected to old alternator wiring harness) (The red wire was also connected to old wiring harness)
Right so you're asking about the red and black wires in the picture above? And the black wire used to connect to here:
And the red one used to go here:
I honestly have no idea what they are for. You said the truck has tow package, so it's possible one (should be the black one) is the constant 12V power supply to the trailer connector and the other (red) is the power supply for the electric brakes controller. They do appear to be awfully undersized for either of these tasks, but that's not something Ford's never done before either. From electric standpoint the red one is getting constant battery voltage, the other one could be also but you're best throwing a meter on its stub in the old alt harness and checking if it's giving you continuity with the big black/orange wire with the ring terminal on it.
Right so that fat yellow wire on factory form bled current current off the alternator's charge wire then split it along the green and orange wires and send it down thru the fuse links to wherever. So add a ring terminal to said yellow wire and hook it up either to the starter relay (the stud where most wires are connected to) or extend it to reach the battery's positive terminal.
Your gauge is an amp-meter indeed, don't one what to do with one tbh, all my 3G conversations have been on voltmetered vehicles.
just confirming this is the starter relay correct?

Possibly? Has the right shape, but I'm used to seeing it up on the fender where you're other big solenoid/contactor/relay (what's that for?) lives currently. Follow the big cables, is one of them leading to the starter? That's your most surefire way of figuring this. And obviously there connect to the stud that has the battery cable on it, not the starter side.
Or you can just connect to the positive terminal of the battery instead. That's how mine has been done for ages, that's how I've always done them - EVERYTHING connected to the battery, or if something must be left on the starter relay (usually cause wire can't reach the battery) then the short cable between the battery and the relay gets replaced with something properly far, preferably the same 2ga cable with copper ends that I used to connect the alternator I the battery.

At the top of this photo the large wire connecting to the battery is running straight to the starter and at the bottom of the photo this black wire is connected to the starter as well, that being said would I be connecting the yellow wire to the solenoid on the fender or the one mounted on top of the wheel well?
Looks to me that the solenoid on the fender is the starter solenoid. The second one must be controlling something else? My initial guess is its a constant duty solenoid and shuts off power to everything else when the ignition is off, as usually the mess of wires on the other side of that solenoid are with the wire from the battery (Ford cheaped out instead of using a separate junction block ran a bunch of fusable links off the solenoid post with the positive battery cable)
Is the yellow wire you are talking about the one in your hand? Its fine going where it is so it is connected to the same place the positive battery cable is.
