Hello, did you ever find out where the wires to the charging light go. I'm doing the 280Z 60 amp alt. upgrade with the jumper plug , which has a diode in in , that plugs in to the voltage regulator connector. a lot of bits and piecing together of info. This shouldn't be that hard. I think the charge light should definitely be working. If you know can you let me know. I'm am going to make this work some how. Thanks, Bill.
