Please help!

Hi, I thought I labeled all my wires when I took my battery out but I missed one! It is yellow and leaves the MPEM unit directly to the battery. Can someone look in their boat and tell me if it goes to negative or positive? I would sure appreciate it. I don't want to put it on the wrong terminal and fry the MPEM.

My boat is a 1997 Challenger 1800

Thanks!!!!!!

Yellow should be positive, all gounded wires should be colored black. Other than that, looking at the wire diagram the only yellow wires are located by the magneto. NOTE This is from past knowledge, I didn't go look at my mpem!!!!
