You have answered your own question . If you think of a "y" harness ,so the one plug end is the rx connection & the other two ends go to the servos . So instead of that you will have a [ depends on size of plane] 5 /16" dowel , length to suit - one end will have a threaded end for a 2/56 or 4/40 clevis , it will be wrapped with cotton & secured the normal way to the dowel . this goes to servo . from other end of dowel is a forked two wires for the 2/56 or 4/40 clevis '. you will have two slots cut in side of back of fuse to allow them out to align with horns on elevator . You will have to juggle the 2 wires out thru the slots , make sure they are free , & not binding .
