I bought an A/C Compressor on Ebay...looks like this...

And the Factory Looks like THIS

Question is...Do I need that light blue connector and if so, How do I remove it from the old one and install it on the new one?

 

Yes, you need to transfer it to the new compressor if you want the new one to work. There is a snap ring that holds the switch in place. Make sure you check the oil in the compressor, and add if necessary. PAG 150 oil ONLY!

 

How do you remove the snap ring? I hope thats not a dumb question lol
