I put my obd2b gsr motor into a 2000 model ob2b ls shell and have this plug left over on the engine wiring harness on the drivers side shock tower, with nowhere for it to plug in to the shell, does anyone know what this plug is for? The picture is the plug in off the old 2000 model gsr shell.

 

anyone know?

 

I believe its the cps crank shaft position sensor located by the oil pump.

 

Red - EVAP Purge - A15
Blue/Red - CKFP (crank fluctuation)- C1
White/Red - CKFM (crank fluctuation) - C11

 

thanks!
