So my Google serch didn't turn up anything so now I'm asking here. I am geting ready to pull the lower dash to run a signal wire for the reverce light switch and the coax for my cb. What I want to know is if the empty fuses under the dash are wired already and if I can use hem to run my cb and power to he switch panle.

There's no 'protected' pin on the empty positions, so nowhere to attach to. Best thing is to grab a Blue Sea (or similar) and feed it from the battery.

If you're only going to add one or two devices, then a piggy back fuse holder may be an easier option

I have a full fuse block and relay board that will be going under the hood but I need a switched power source for the actual switches themselves to run the relays

I'd use one of the piggy backs as a source for the switches triggering the relays. Take the feed from the fuse to a terminal block and split it there so you don't have to double the wiring at the switch. Will make additions easier.

I'm just trying to avoid the fuse taps becaus I just realy hate them after using them all the time when I worked on fire trucks

So this blank slot has both pins in so it might be wireed to one of the blank pins on a plug on the block which means that I could hook I there and it should be a live on ignition. I might just pull off the power for the stereo to run the cb so that it's on with acc but that is only if it retains station memory without power if not it will be going in the other slot which should be a constant power slot

My truck had 2 (maybe 3?) open fuse holders that already had power, one constant and one ignition switched. I used the add a circuit fuse holder that plugs into the fuse slot so I had a pigtail to get power for my switches (didn't feel like taking stuff apart to figure out the backside)

Well I am already taking apart the dash to run coax and a signal for my reverce light switch so it's not that much farther to pull the fuse box and run a continuity teat to trace the pins. I miss working on internationals, they have 10 empty fuses for adding on extera circuit.
