I have a 2001 ford ranger (2.3 duratec) with a 98 ford explorer 5.0 and a fox body t5. It runs well and seems all functions are working but the oil pressure sensor is reading on the coolant temp gauge and when I ground both the coolant and oil pressure sensor they both read on the coolant temperature gauge. is there some repining required on the dash. I also hear something about the tachometer needing to be repined to work but it seems to be reading something at least.
