it would make the resistance value change!
think about how the meter works it uses a voltage to measure the resistance by reference
so if the car has a bad earth the meter is being effected buy the introduced voltage by the car feeding back through the high resistace joints
pin 4 + pin 5 are wired seperate to a joint (EM34A) which goes to Joint (EM34) which goes to Earth point (MC34)
so maybe buybass all the joints go Pin 4+5 to earthpoint
im trying to locate the earthpoint but am having issues locating it
autodata says its in the drivers footwell
