Yeah man no problem. It can go anywhere on the engine. Just take it to the firewall. I'd still go off of the pass. head. It's easy to get to.
Here is the info I collected when I added mine.
I felt for the lifting bracket and it was just lower of the allen to the left side ( of the lifting bracket that is, say about 7 o'clock ). The OEM ground is 30" about, I think 12ga but you can always go little bigger, and the motor bolt is an M10-1.5x12.5mm long ( 1/2" long) and the firewall bolt is M6x1.0x12.5mm long ( 1/2" long) I went with stainless and used some no-ox on the terminals to help with corrosion.

Yep, I remember. I posted that vid as it was the same setup you have.
It's never going to be and shouldn't be over 14 all the time with general auto batteries. I really only use the plug voltmeter to ensure my alternator is working. Most the gauge readings are elsewhere. It also has colored LEDs to warm of under volts.
That plug is accurate but like all harness values, it a tenth or two below off the alternator. But it's way better then the OBD port values. My two ports read differently, one lower the the other, again as they have different harness positive and negative points.
I'll note the locations in the next days

It might calm you down a notch about your electrical system.
There may be better ones out there, but this $10 little tool has served me well in checking, diagnosing vehicle electrical systems, both friends and family as well as when trying to find a used car for my grandkids. Plug it in and see what happens on a quick test drive.

Certainly you checked this since you just changed the alternator, but is your belt tensioner good? Mine was bad causing intermittent low voltage. The tensioner would relax under load and wouldn't tension again on its own. When I went to remove the belt I pulled on the belt and the tensioner unwound and just stayed like that allowing me to remove the belt without holding the tensioner. I can't believe I didn't lose the belt on our 1500 plus mile vacation.

Oh no mine returned back and a good pace and seemed to lock the belt tight. But from what Ive seen here, the 13.6-13.8 is the normal. Also I gotta keep in mind that I have a 1800w audio system too.

Fwiw, my sgII usually showed about the same as what you report. 13.6-13.8 sometimes 14.0. Not usually much over 13.8. When my tensioner was bad it would dip quickly under 13.0 to around 12.6 or 12.8 periodically.
