After market radio hook up in 73 valiant

So here my plan I hopefully figured out. There is a spare section on the fuse block that is unused, in the manual it says it is an accessory slot and I have tested it and it is 12V ignition Run. So I think I will run power there. As far as the yellow wire for presets I will undo the cigar liter at the fuse panel and run a pin from it to the radio. Both wire I will use 14 ga wire with inline fuses after the fuse panel fuses for insurance. If anyone thinks part of this idea is bad please let me know. To me is sounds ok. Im good at mechanical work but I hate electrical even though it probably isn't that confusing lol
