FIRST TIME BOAT OWNER AND I NEED HELP WITH ELECTRICAL ON 88 TSX17 TRACKER

I BOUGHT MY FATHER-IN-LAWS BASSBOAT THAT HE HAD FROM NEW. I AM TRYING TO FIGURE OUT THE WIREING ON THIS 1988 TOURNEMENT TXS17 BASS TRACKER WITH A 75HP MARINER. I USED THE BOAT FOR 2 YEARS AND LOVE THIS BOAT, ( CHEEPER THAN A NEW BASS BOAT RIGHT? ) BUT I HAD TO REPLACE THE WOOD IN THE FLOOR AND DECK DUE TO OWNER NEGLECT BEFORE ME AND I NEED TO REDO THE WIREING WHILE I HAVE THE WOOD OUT OF IT BECAUSE IT TO HAS BEEN COBBLED UP. PROBLEM IS I DONT HAVE A WIREING DIAGRAM OF THIS BOAT SO I DONT KNOW HOW TRACKER MARINE WIRED TOGETHER ALL THE GUAGES AND SWITCHES FOR THE COUNSEL. IS THERE SOMEONE WHO KNOWS HOW THE COUNSEL IS WIRED TOGETHER WHO COULD TELL ME HOW TO DO IT? ALSO FOR A WHILE THE TACH WORKED FINE BUT ALL THE SUDDEN QUIT WORKING--ANY IDEA WHY? THANK YOU IN ADVANCE :) ADAM
