Re: Wiring diagram of instrument cluster

The gauge cluster does not have a light since it has a regular temperature gauge. The wire for the light was on pin 5 and has been moved to pin 6 for the gauge cluster. The sender was changed to allow for variable resistance to ground which gives the different temperature ranges on the gauge.
