Raptor Shift Light Install-Ram SRT10

 

 

The switched power source came from circuit F984 pink/yellow at connector C220 pin #14 under the dash to the left of the clutch pedal.  Ground just went to an IP brace.

  

The tach signal can be picked up at the PCM located in the passenger rear of the engine compartment.  There are 5 different coil driver circuits that can be used all located in the black PCM connector C1 (the bottom connector).  Any one of these can be used...

Pin #5 is circuit K134 dark blue/yellow for coil control #5
