Let's see if this schematic helps. It has the wire colors, pin numbers, etc. for the PCM, Camshaft Position Sensor and the Camshaft Position Solenoid.

Hi thanks for the info but if your attachment has only one page it does not show anything about the cam sensor or the cam solenoid If I am doing something wrong please let me know

Actually, it does show the cam solenoid which is what your message, #3 in this thread asked for. It is labelled as C2, pin 39, cam pos sol hi. Follow that brown wire to the solenoid.

The sensor is not on that diagram though.

Do you need the sensor wiring as well? I would proceed cautiously and check the wire colors etc to see that they match your 2007. I think there are differences between years.

My apologies, I misread the crankshaft position sensor as the camshaft position sensor. Attached is the schematic which does show the camshaft position sensor. It's at the bottom of the page on the left side.

I know it's for a 2004, but it should be close enough to get you going in the right direction.
