Normally you have red for+ and black for - .
i am afraid to connect it the wrong way, i think it does not have protection for inverted polarity.
Use a magnifying glass to look at the writing on the power supply that came with it. There will be a symbol that looks like a capital C with a line coming out of each side. It is a representation of the polarity of the plug.
Also be aware that 99% of these have + on the center pin. I have heard exactly one report of one wired the other way, but I believe that report may have been wrong.
