I just had to replace my ignition switch/key asym in my car yesterday. Yes it is a Urraco but the parts manual lists the same number for the Urraco and Jalpa. I used a Fiat 124 Spider 1968-1977 switch asym - direct replacement. However you do have to make jump wire for the main power supply. On my original switch the main power supply is one terminal. On the replacement it is one for the run position and one for the start position. Use a multimeter and figure out your terminals.
