[IC27A] i'm crazy, but are my wires crossed too?

[RobAdkins]

hi all,

depth sounder woes. i'm in the process of reinvigorating my DS45 and need to 
bypass a splice that runs behind the bulkhead and is therefore out of sight. 
i'm splicing the transducer cable (four colors plus a bare wire) to a 2 color 
cable (black and white with a bare wire) that connects to the head unit. does 
anyone know which color goes where? i would use the previous splice as 
reference but like i said i no can see it. thanks in advance. -rob
