dash

Hi, I just bought a 2002 Bennington pontoon that needs fixing up, but I am finding very very little information on the internet. Almost all of the dash does not work, wires are hanging all over the place. only the battery gauge works. not even the horn works. I can't find a wiring diagram or...

I have a Bennington Pontoon. Just got a different one in fact. When I flip the master power switch on the dash, should it really reset the radio??? Drove me nuts on the 2011, same issue on the 2013....a friend had a 2002 with the same issue we learned while we were talking...I cannot believe...
