On my non turbo gs spyder the rear o2 sensor follows the exhaust, comes up by the axle and has the harness connector right by the ac compressor. Then it has a harness extension from there to the top of the manifold where the other connector is clipped on to a bracket right the crank position sensor and the vacuum solenoid. My connector is different from the turbo's rear o2 sensor. My connector is the same as the front.

Btw, the rear o2 harness goes through the body on the turbo and that should be the connector for it in your pic

Go to sparkplugs.com and it will show you a picture of the connector.
