not 100% sure if this is good to do as there's no glow plugs in 1hd-fte.
fusible links are designed to be "Slow burn fuses" so I'm looking for input to what people have done.
I see what's going on that cable goes to the second battery then to the 24v switchover for the starter. If your plan to leave it factory as Toyota intended you can wire direct to second battery as per diagram no fuseable link needed
It's been a while since I looked at mine as I also have a 12v...
If you cannot find your Fuse-able link you can follow the alternator wireing battery to the side of your battery box. It should look like this. A black fuse link distribution box and a Grey connector next to it.

Thicker cable won’t hurt especially if you have lots of accessories. I run 1/0 ga
Fusible links you don’t need to change.
you can also get pigtails to convert 3-pin round to any other end you want
example a 3-pin round Nippon Denso to an oval plug
Good call on the bracket looks like you...
