My truck has the gauges package, which includes a hard line to the oil pressure gauge.

The M&H engine harness I bought has the blue wire that would otherwise drive the idiot light. I'm -guessing- that this is unused and should be just taped off, unless I wanted to get fancy and add my own light somewhere.

But does anyone know for sure what the factory did? Or was there a different harness for trucks with gauges?
