I have a 2010 xlt. I bought the exact same used gauges and swapped them out. But now the truck won't start and the car&lock keeps flashing. I also have an after market security system.
Any way to fix this

Thanks

 

you need to have cluster reprogramed,system has the pats key security programed to the cluster, put old cluster in it will start and you do know that the mileage on your new cluster will not match the old one..
