I put new terminals on my batteries and cleaned everything up and now my truck starts fine but the windows wont roll down the air conditioner wont blow the speedometer quit and my pyrometer quit. i checked all the fuses and the connections on the batteries and the main power to the fuse box. It is throwing a P500 code that i havent looked up yet. If anyone knows anything please help me out

 

P0500 = No vehicle speed sensor signal present
Check wiring on left side frame rail back to center of rear axle for damage
