Instrument cluster failure

Hey all, I recently installed differential lockers in both differentials of my 2002 tundra. After finishing assembly and test driving a few times locally, I decided to get bigger tires. So I had one of the big chain guys install tires in the truck and while it was there I asked if they could do a lift kit. They gave me a good price so I had them do it. When I picked up my truck the dash lights were dead and several instruments did t work (wipers, turn signals, stereo, and perhaps some others). The tire store said it was like that when I brought it in. So... anybody have any ideas what could be the issue? Thanks!

 

Start by checking your fuses.
