Fuse size head unit + oil pressure gauge

[ViPER1313]

The stock wiring is abysmal, I ran a straight wire to the head unit and it actually made a noticeable difference when the system was cranked. Hell, the LCD on the unit would dim with the stock wiring on a bass note at high volume. The wire you wired it to (and me subsequently rewired it to) is well routed and looks to be in good condition. I don't know what grounded out, I was careful as hell running all this stuff, soldering / taping, etc.
