I have a '97 F150 Lariat and the lights seem to come on prematurely. I have not been able to find the sensor. I understand that there is a senor build into the blinking light on the dash. On my truck, I have a blinking 'THEFT' light when the alarm is activated. Is the sensor behind the tach or some other place.

What's involved in changing the sensor, or is there an easier fix. Thanks, Mike
