2002 Journey starting problems

So, I was having trouble betting my2002 Winnebago Journey 32 T to engage the starter motor. Just clicked. Replaced batteries. Still clicked, before I was cleaning up terminals on the starter and something (a relay I thought). on the chassis that I thought might be related. When I tried To take the terminals off it basically broke apart. I am attaching a picture of it before and a couple after. When I jumper the two wire terminals, the dash comes to light when you turn the key and the starter engages. Have not gotten it to start yet but I think that is another issue. But if I do not jper the wires together, the dash is dead when I turn the key (and it does not engage the starter). I see on a broken piece where it says aux batt so I suspect it is related to the aux story circuit.
Does anyone know what it is and where I can get a replacement?
