So i have been having this confusing problem with my toyota. The gauges and LCD on the dash have some sort of brownout going on which causes them to flip on and off during driving.
Additionally, the dash will shut down when trying to do the following:
-Wipers (front and rear)
I have found the dash power terminal and it appears to be getting 8 volts when operational, 6 volts when flickering and 0 volts when non-operational.
How can I fix this? Can I just splice in another 12v ignition activated wire into the power wire I found?
