guages

Edit: Its a 2009 Ram 1500 Sport 5.7L with 170 000 km on it. Hey guys, I was hoping to wait till warmer weather to fix the electrical problems on my truck but I feel if I wait any longer it's gonna be sitting in a parking lot dead. It started with just the SVC 4WD/ABS and traction control lights...

I replaced the heater core and a/c evap. core this weekend. When I put the dash back together none of the ghauges work. Brake lights are also not working, but all other lights and flashers work. Also the windshield wipers work but not the washer function. I assume I have an electricial problem...
