Hey team, I am at a loss on this. The wiring diagram for my Sport XRC shows JB1, a 3 screw terminal block under the dash, and specifically terminal 3 POST_ACC as the 12VDC supply to, I would imagine, add on accessories. The color code of the wire that feeds this terminal, W453, is purple (not the actual color of the wire, which is RD/BN), and according to the definition table for these diagrams, purple would mean a switched wire. On my rig this terminal is constant 12V, and not switched at all. Is this the norm out there? Is the diagram incorrect? There certainly are other wires and, for example the extra 3 pin connector for the winch remote, that have a switched wire 12VDC. I am only wiring in a 2 port USB charger, but even that should not be powered unless the rig is running. As an alternative, and because I like this little easy to use fuse block, I am taking power for my accessories off right down at the battery. This little fuse block fits perfectly under the seat, and could go directly on the battery terminal, but then it would, just like the terminal 3 mentioned above, be hot all the time. To fix this I will use an automatic battery isolator that will turn on at 13.4VDC and off at 12.9VDC. I already have the thing from another project where I did not need it, so no big deal on the cost, as it's pretty $$$. In the end, my entire accessory circuit will now be powered automatically through the isolator when it sees 13.4VDC, and shut off when it drops to 12.9, about 2 minutes after the ignition is turned off.
