No, "hot" is just the opposite of ground or neutral. All modern cars have a negative ground, so positive is hot; however, decades ago some were positive ground, so negative was hot in those vehicles. That reversal of normal practice is the potential issue.

That's what is needed, and I agree with Tom that it is wise to check.
