yeah, it basicly tells you there what color the wire will be in the location of the speakers. they are the same at the head unit as they are at the speaker. anyway, something you can maybe look for is + is usually a larger connector, the - is a smaller connector. that's sort of easy i suppose.

if your going kappas, then you prob have a newer deck.
I strongly reccomend rewiring the complete stereo system, you'l see the diff

ok all this aside the little connector is the negitive if thats any help

I just looked and the old owner must had a system in there there is new wire if there is a line on the wire thats probaly positive right and if not how can I check the polaris of the wire

Just check where they tie into the adapter for the HU.

Or use a small battery and watch as the speaker moves out. That would mean that the poles are correct. If it sinks, swap poles...
