I like to add my own wiring that only connects to the battery and the frame for ground. On most bikes I use a marine style fusebox but on a KLR that's hard to do. Space is so limited. By adding my own stuff, I know that I'm not splicing into something that might cause an issue and one main fuse kills all my stuff if there's any issue. If I need "key on" power, I use a relay and splice into the running lights to power the relay coil. I hate seeing wiring where there's 6 hots on the battery post. On my KLR, I ran a large hot wire from the starter solenoid and covered the wire in rubber hose as an extra insulation. I figured that way the battery would only have two wires on it and the connection at the solenoid would never have to be removed. Splicing in all over the bike for all the extra stuff you add (and will add) may cause you issues down the road. As time passes, you may even forget where you tapped in to power (INSERT DEVICE HERE) and have to figure out WTF you did a year or two ago. Buy red, orange and black wire. Red is hot. Orange key on hot. Black is ground. Leave room for the next electronic DooDad the some geek invents that is a "must have".
