[IC27A] Electronics mounting at the wheel helm

[PAUL]

Hi all,
Need more advice from you seasoned skippers.  The boat I recently purchased has 
a through-hull depth-sounding transducer but no depth gauge.  I've found one at 
a local boat electronics store that works with the transducer when powered.  I 
think I can find a bracket to mount it on the guard above the binnacle compass. 
 Need some wisdom on running the wires from there to the fuze box and 
transducer.  Will I have to drill a hole in the pedestal or is there another 
way?
Thanks!
Paul
