2017 Commander – Hard Wiring CB / Other Accessories

I have a 2017 Commander and want to hard wire my CB instead of powering it from the aux power port (aka the old cigarette lighter method). Is there a way to tap into the fuse box or do I need to wire it off the battery with a separate fuse. Since I have other things I'm going to add (e.g. horn, lights, etc) I really don't want a bunch of stuff running directly from the battery if there is a way to take advantage of the fuse box. I pulled the cover off the fuse box but didn't see anything familiar to get power from. Thanks...

03 03 700 twin speedo

I have an 03 sportsman 700 twin, the speedo works, but the digital part only shows hours, Miles and gear selection, is it supposed to show fuel or rpm's ? I ask because I just rebuilt the carb and trying to set idle I have no way to set to an rpm range, maybe that year doesn't have it or my speedo is bad, sorry this is a new quad to me.
Thanks! Derek

Help!!

I have a 2008 outlander max xt and it has a back fire everytime i press the gas. I replaced the spark plugs, put a new fuel pump, cleaned out the gas tank and put new gas, did an oil change, and check the compression. The compression on one side is 150 psi, but the other side where was none at all but it starts and idles at 1400 when cold and when warm at 1250-1300rpm. Any suggestions what else i should check? Spark is good also on both sides.
