Lost all gauges on an 03’ international 900i

[Redland1]

I disconnected the batteries yesterday and somehow I missed the negative when hooking everything back up.It started up one time but when I went to start it a second time the power steering hose started smoking so I l knew then it used it as a ground the first time to start.So I started to look at the ground wires and for any power wires with exposed insulation touching the chassis and that’s how I found the negative disconnected.Hooked it back up and turned the key to realize that I had no power to the gauges.How can I get them going again?
