I'm trying to wire up a CB in my Runner, but my knowledge of auto electric stuff is very limited and I could use some help. I want to wire it into the fuse panel under the dash so that it will power off when the truck is off. I bought one of those wired fuse plug things to connect to the + wire of the CB and plug into the panel. I was thinking I would either plug it into the radio or cig lighter fuse plug. When I pulled the fuse box cover off, I don't see either of them on the diagram. Just 4wd (20A), ECU-IG (10A), ACC (15A), Turn (10A), Wiper (20A), ECU-B (7.5A), Guage (10A), and IGN (7.5A). Where should I plug this thing in? Also, the CB manual says to run it on a 2A fuse, and none of these are 2A. There is one open slot on the upper-left, but the panel diagram just shows a line going through that slot. Not sure if that means that the slot has no power, or just isn't reserved for anything. Can I use the open slot, and if not, which one should I use? See attached fuse panel diag.

TIA,
Andy

Thanks for the help... I'll give that a try.

Thanks Bump, I didn't realize before I opened the package on the circuit tap that it has two slots. I did exactly what you suggested, and it worked great... I have a functioning CB now... thanks for the help!

Followup question... how would one add another aux device? Obviously it wouldn't be a good idea to plug a circuit tap into the existing circuit tap. If I wanted to plug in my GPS, would I have to add an aux. fuse panel, or is there an easier way?

Just a tip for the future that may or may not make it easier. Instead of messing with the fuse box, for an easy acc tap, i go to the radio harness.

That sounds like a good idea....How would you go about doing that? Could you just splice a wire with an inline fuse into the red wire that goes to the harness? Sorry if this is an obvious question... I know nothing about car stereo wiring.

Another related question... say I want to wire up my gps, or anything else that has a 12V cig lighter plug. I don't think I can just cut off the plug, because the output voltage is lower (I think it's like 1.5V for the GPS) than the 12 input voltage. Do I have to figure out a way to connect the + and - wires to the cig plug? I'm hoping there is a more elegant way of doing it without keeping the cig plug.

same thing. Pull the cig lighter out, it will have a black wire and a power acc wire. tap into the acc wire. You do need to test it though. I have worked on some cars that the cig lighters get constant power. Test with an volt meter.

As far as the radio, i can recognize what the acc and power and ground look like. They are all basically the same on aftermarket radios. If you are unsure, again, hook up a volt meter and test the wire you want to tap. Make sure it reads 0 when the key is off, ~12 when the key is turned to acc and ~12 when the car is running.
