i searched. I asked a few guys locally.

but just making sure there isn't a easier place.

i wanna power my pressure guage for my bottle so the light turns on when i turn the car on or turn the key the light comes on.


so what wire should i slice in the inside?

 

run the power wire to the inside fuse box on the passenger side. use a mini add-a-line with 2 ATM fuses and replace your wiper fuse with this. crimp your power wire to the end of this and your done

 

^truth, that fuse is the easiest to tap into. Comes on when the ignition is on
