I took ownership of a two state room two head 2007 423 with a missing hand held shower fixture in aft head on the left side of the sink. Just the hole there for the shower head to rest into. I want to correct the shower plumbing back to original but can't figure out how the shower hose was originally plumbed into the fresh water system with a hot/cold mixer valve. All I see underneath are the H&C feed lines to the sink faucet assembly on the forward side of the sink. Any photos of original water line plumbing would help if no one has a schematic with parts listed would be greatly appreciated.
