First off, howdy and welcome to TTZ big tim! You'll find a lot of Gen 1 Tundra owners here, so we're glad you found us.

As to your problem, I would check to be sure there is power to the back of the radio (if you can't get to the supply wires, you may have to pull the radio and see if you're getting power to the radio itself). If you have power to the radio, then it is a radio problem (possibly the radio has a fuse/circuit breaker?). If you don't have power to the radio then you will have to troubleshoot where the power supply is broken. Some Gen 1 folks may want to jump in here on this problem!

I may have some drawings if you need them?

Rarjar is right, power and ground is always needed to complete a circuit so check for both of those.
