Wayne, You will have to replace the electrical connector plug. The Ducellier uses a connector all it's own. When you are done, you should have one wire left over with no place to connect it to the Motorola alternator because it is internally excited. On the Ducellier plug there are two wires: a brown with a yellow trace and a heavier all brown wire. The brown with the yellow trace connects to 'L'. The heavier brown wire should be taped off and not used. And if all this blows up in your face, don't blame me :) It is my experience that all alternators in the Delorean use the same belt. Here are some cross-reference numbers that you may want to try for the belt: Dynaflex 15495 Gates 7495 Nationwise 49013 Walt Tampa, FL
