Wire Gauge?

[Quarterwave]

Hi everyone,

I need to run some extensions from my wiring loom and are hoping that someone can help me to determine what gauge wire I'll need - please see the pic attached for reference.

Red = ?
Yellow/Red = ?
Orange = ?

Any help is appreciated in advance.

the Red is main system power and I`d say #10
Orange is alt feed TO the battery usually a 10 Ga and should have a merc fuse link or a Maxi-Fuse installed
Yellow/red starter solenoid 12 or 14

Thanks BT!

look up battery gauge size and measure what you have

Cable size is determined by length and amperage. If you add xxx length to your XXX size cable, it could create a fire if the cable is not the right size.
Not sure what those cables are for, or how much extension you want to add, but you need to figure out what amperage you will be seeing and the length of cable you need. There are multiple guides out there that can help
