I used a seperate switch and charge jack mounted on opposite sides of the fuse, with a home made holder for the switch, and only a 1/10 diameter hole for a wire running through the fuse to the switch. I think I can mount the remote glow connector at the bottom rear of the cowl on one side, with a round notch at the back of the cowl for it. But the fuel filler is trickier because if I mount it aft of the firewall I will have to plumb it behind the firewall and drill another hole in the firewall in another location to run the fuel tubing from the filler to the carb. Additionally, the way I have seen YS engines rigged is with a "T" in the pressure line, running to a externally accessable fuel dot so as to release pressure before refueling or when finished flying, so I will also need a place to mount this fuel dot. "Almost Ready to Fly' is a rather big "Almost" sometimes, eh?
