iMac 11,2 (mid 2010) 21" HDD Sensor Bypass

[90Ninety]

So I am trying to understand the below article, and replace the old Spinning Rust with a Nice SSD . Though the article is confusing , my iMac does have a cable running to the Jumpers on the Samsung HDD ( something the article suggests is only on the 2011 model - despite mine being 2010 )

The cable is just simply two wires, shall I simply just jump the wires, or do I have to bridge the SATA pins also ?

Thanks in advance

To my understanding you do not need to do it for the 2010 Model but as the Pins are just Com in Normal Configs you will do no Harm anyway:

One has developed a solution that eliminates the 4SNS/1/40000000:TH00-9.000 problem after replacing a HDD in the following Apple models that do not have an external drive temperature sensor:
- iMac 21.5-inch A1311 (2011 model)
- iMac 27-inch A1312 (2011 model)
- iMac 21.5-inch Retina A1418 (2012, 2013, 2014, 2015 models)
- iMac 27-inch Retina A1419 (models: 2012, 2013, 2014, 2015)

Fig.
Figures 1 and 2 - Pinout of the SATA power connector (left standard pinout, right Apple pinout).

Solution:

Simply connect pin 11 to pin 12 of the SATA power connector with a drop of tin before installing the drive, as shown in the figures below:

Connecting pins 11 and 12 of the SATA connector (on the left a 2.5" drive where the solder joints of the connector are accessible without removing the electronics, on the right a 3.5" drive where the solder joints are inaccessible from the outside and the removal of the electronics board is required)

Just jump the wires. I did this on all of my iMacs. No need to worry about them.
If you want to go some extra miles for no reason at all, you can buy ODD sensors, cut the wires in the middle and join them together.
