My friend has a 98 GSR swapped into a 95 LS. The car was missing a map sensor when he bought it. The map sensor he bought matches my 95 LS. but it will not plug up to the wiring harness from the motor. I wasnt aware that the map sensors were different. ok, so im trying to find out if this car needs an OBD 2 map sensor(if they are different) or if the wiring harness is the problem.
