Is this factory 1975 stuff

Just an FYI.... it takes well under 1 amp to kill......but 12V can't push any appreciable current through any part of you. The lowest voltage documented to kill is something like 42V an only in special conditions. So don't sweat that too much.

Some of the responses are not ideal.... but expecting free help to behave in a certain way is not realistic. If it was paid for, that would be a different kettle of fish.
