Recently acquired a 92 with 140k miles. I have big plans on my build and one of them is installing a custom gauge cluster. My current speedometer is not working jumps from 5-15 mph only for a few seconds after a cold start and acceleration.
Id like the important gauges, Speedo, Tach, Oil Pressure, Oil Temp, Water Temp, Air Fuel Ratio and Boost. I under stand how to wire up all of them except the Speedo. Am I looking for mechanical or electric for simplicity? Any additional info is welcomed.
