Some electrical questions

[danny_holtermann]

I have two options for wiring up some leds and a line-c. The Wire i will be using so i don't have to run a wire from the battery is wire 38, which is bk/o. On that wire it has 50a, or the other wire i could use is the wire 37 which is yellow, that is 40a. This all could be absoulutley useless and not matter, but i thought i would ask which wire to take and use.
Let me know what ya think
