Simple fix when the issue is with the circuit board in the cluster. Splice in a 5 volt source to the dark green/yellow stripe wire coming from the connector on the left. I used a 12 volt source reduced to 5 volts. The problem is the solder connection on the printed circuit. This is an easy fix. If you check the voltage on this wire, light on, it will read less than 2 volts. It requires 5 volts to keep the light off. E-brake and low brake fluid warnings will still function as intended.
@@thegenius653 thanks. That light is about to drive me nuts. It just started going on and off last week. On a good note it is 30 miles away from 200,000 on the odometer. I should cross that mark today. Very good truck. I'll celebrate by fixing the light lol
