battery cable confusion

[chengkhang]

i just bought this 92 sc400,.. from some guy,... and some how he got the battery cables mixed up,.... i found that out when i was check out the battery cables,... he had the cables crossed,.... and now im not sure whats whats,.....

there is 3 cable, i know for sure one is + but not sure about the other 2,... one seems to go down under the ac pump, that i think is the ground - ,... but whats the other one,.... ?

where does it go to?
what gauge is it? Could be for an old sound system or something...

when you say "crossed" what do you mean by that?
