Engine bay wiring

G'day all, doing some engine bay wiring on my 92 rb patrol and just after some info.

I'm currently making up a fuse box for the engine bay, I'm upgrading the alternator and running it through new wiring with an midi fuse. I'm just trying to work out what size fuse is needed for the main power going from the bay to the fuse box (the white with red that connected to the green fusible link straight to the battery) as i plan on replacing all of the fusible links with midi fuses.

I've gone away with the carby and i am running straight lpg so the "PTC Heater" isn't needed anymore, but ive found another brown one near the relays that connects a white wire in and back out into the loom, what is this one for?


Are there any other fusible links that I'm missing other than alt and main power? if so does anyone know what their currant rating is? It's so hard to find solid info on the fusible links, thanks for any help :beer:
