I'm building my 5.0 engine to drop into my 93 2.3. I have my lower intake on and valve covers and I'm installing the fuel injector harness. I notice that the plug for the ACT sensor plug is on the left side rather than on the right side like the 94-95. My lower intake is from the 95 gt and it's not drilled and tapped for the sensor. My upper intake is from a fox body 5.0 I pull one of the vacuum ports from the front on the upper intake and installed the ACT sensor there, which should be alright.
What are the two vacuum ports on the front of the upper intake for?
