Thanks

On most older builds all that does is parallel the house battery to the starting battery. So no it will not hurt. What is important to know is most of these setups are intended to assist the starting battery. Unless you know the size bus wire that links the two batteries is large enough, an undersized bus can get pretty hot when cranking the engine if the starting battery is very low or dead. Just like using jumper cables, sometimes you have to leave the cables connected for a bit to help the starting battery regain some of its charge before attempting to start the engine. Not sure about your relays.
