My 2000 tundra v-8 has some issues. The dash and head lights flare with rpm. When it rains the alarm goes off. Idle drops and truck stalls when put in d from p. Parking lights will stay on with key out of vehicle and all switches off. Looking for wiring diagrams for under dash wiring components. Any advice on where to start would be really helpful.

 

Check your battery...I know how it sounds but you might be surprised how often it is the problem.

 

replaced battery. all issues solved- thanks

 

Noobie Gooberclese for the win!
