looking for any info on layout of head hoses for 1986 419 CC

[SAOIRSE419]

With boat just over thirty years, (owned 3 years by me) it is time to replace the hoses to both heads on m;y 1986 Moody CC 419. Daunting..... and afraid....laughing. Have read the tips and

It is not clear how the hoses run and where they go. For the head closest to the bow, can trace one of the hoses the short distance to compartment in vberth. but cannot trace second hose. Not sure if I really need to take down the cabinet but not sure. The less I need to figure out how to put back together the better.

Anyone that has done this on similar boat, would appreciate any/all advice. Am willing to do the sweat equity, just not sure i an put things all back together if i have to start tearing things apart.

the head near stern in captains quarters seems little more straightforward and able to trace the hose straight up to tank.

appreciate all advice.
