    So with all of my googling and searching of this site, I couldn't find info on which fuses were 'ignition on' or not. A month or so ago, I installed 2 dual battery relay isolators for my setup (one for my aux battery and one going from aux battery to my aux fuse panel) and hooked them up to what were fuses that I thought were turned on when the ignition was on, but when I went on vacation for 4 days, I got an email from my house-sitter that my trucks battery had flat out died. They had AAA come out and do a diagnostic on it and the guy said he had never seen a battery so dead. Something drained the hell out of my main battery, and I think it was the fact that my isolator had never turned off. ie: wrong fuse tap dummy.

    So this brings me to my thinking on what I did to get it to that point, and I figured I'd wired the triggers for my isolators on incorrect fuses. I am including a pic of my specific panel for my 2014 DCSB. I had one triggered to 'RADIO NO.1' and the other triggered to 'RADIO NO.2'
    Am I wrong in thinking these were ignition on? Are these always on? What fuses on my panel can I tap to allow the system to turn on when I turn my truck on? Thanks for the help yall!

    I have a 2014 DCSB and I'm pretty sure there is no fuse that is truly only on with the ignition. The closest you're gonna come is the EFI. It will turn on and off with the ignition but that circuit runs a check every 4 hours for about a minute so every four hours you're gonna get power for a minute. I have my halos on my headlights wired to this and they turn on every 4 hours, I just don't worry about it. I will get calls from friends occasionally telling me my headlights are on though.

    I tested all of the fuses with a multimeter and couldn't find one, but if there is one I'd love to know which one it is!

    thanks for the replies @Muddinfun and @The Boat Oar ! thats interesting that there's no 'ignition on' on that fuse panel. VERY good to know, that makes sense as to why my battery drained so thoroughly! There are some in the interior fuse panel, so I can bring my triggers through the firewall and tap in there. Thanks again!

    do you mind sharing which fuse has power when the ignition is on and no power when the ignition is off on the fuse box in the cab? looking to wire up some amber lights and already used EFI in the front box.

    ACC or any of the 3 20A power window fuses. The drivers door PW fuse is 30A. Leave that one alone.
