I have little 4cyl frontier and it's got some crazy things happening. When the headlights are on all 3 brake lights are lit up. When no lights are on and the key isn't in the ignition press the brake and it sends the alarm off saying headlights are on. And now when press the brake Pedal the running, dash, and brake lights light up. Any suggestions or help. Thanks!!!

 

Hello, welcome to frontiertech...?

Robert, don't you know that Toyotas and Nissans are the same thing?

 

Moved to the correct section

 

Does the rig have a trailer wire harness that's hacked in ?
There may be some shorted wires under the dash.
