I just removed the stock radio in my 2000 blazer to install an aftermarket one and now when i start the car gear indicator wont light up on the dash. All the gauges are working fine except for fuel and speedo which doesnt read anything. The lights come on to illuminate the dash, and when the battery turns on all the check lights etc work. Except for the high beams indicator. The new radio isn't installed yet. That's todays project. I need at least my speedo reading before i have to go into work tomorrow. What did I do wrong?

 

Did you check your fuses?
