im just trying to find a useful 12v wire in my car taht is already connected to the fuse box.


i already have a few items being powered from the 12v wire from my radio

i dont want to put too much off that wire

i have a complete digital dash that i need to power somehow

any suggestions?

if i must wire directly to the battery what size fuse would i neeed to protect my dash?

just alittle help guys

normal size wire that you see all over the car incase your worried about the guage of the wire

 

Camaro or T/A?
Never mind.
The 10A gages circuit has pink/black wires going all over the place. The 10A ECM circuit also has a pink/black wire. Then there's the 20A turn b/u circuit that is dark blue.
There are no other circuits that are powered continously from run through bulb test to start positions of the key.

I can't imagine the dash is drawing much power so I guess even a 3A or a 5A fuse would be plenty. This would protect even the thinnest wiring.
Max fuse size for wiring has been stated quite recently here.

 

so just for ha ha's

if i wired directly to the battery a 3-5amp fuse should be good enough for my digital dash?

if i didnt want to go digging for those wires you mentioed

 

well?
