ok i found out that the sending wires come through the pass. side. can i still remover the 4 cyl. computer and wire the sending units in to the gauge cluster. does anybody know if the 2.3 engine temp sensor is the same as the 5.0 temp sensor, are they 1 or 2 wires. this is confusing. i will get aftermarket stuff one day but i don't want a gauge cluster that has non working gauges.
