how can i get a new Hard Drive Temp Sensor Cable Late 2009 4 pin one not the 8 pin
It depends on which HD you are planning on using here. Apple has three cables for the drives that were out at that time: 922-9215 - Hitachi922-9216 - Seagate922-9217 - Western Digital Some newer drives may require a different method. This when the older HD Temp Sensor cable may be needed. In this case you apply it to the casing near the spindle motor.
