Hi everyone. Before I ask my question, this has been a great resource for my restoration. Here is my question: I am working on a 1970 Cuda 340 and I can't figure out where the negative cable hooks up? I have a reproduction one that has two wires. Where does each of them go? Does one go to the engine? If not, how is the engine grounded? If so, where exactly does it go? Sorry for the amount of questions, but I am trying to get as close to factory as possible. Thanks again!!!
