Not sure about a 1995 column but..the 1991 steering column's have a small snap in cover around the tilt lever that you can remove, then you can unplug the wire harness coming out of the turnsignal stalk. If I remember correctly to remove the turnsignal lever push it up till it locks in the right turnsignal mode. Twist the lever to the right about a quarter turn and pull straight out. Reverse the procedure to install.
Perhaps you can soldier the broken wire. The wires tend to rub on the opening around that snap in cap, When you put it back together position the wires so they curve up or wrap a electrical tape, heat shrink tube or a small piece of vacuum hose around the e wires.
The turn signal levers are generally replaced as a unit. Some people have replaced them because the white wording has worn off ( like on mine ) I've never heard of any levers being disassembled for repairing.
Good Luck
