Well here's the story. when i was doing the swap, the website i went to said that there would be a two prong sensor on the back of my A6 that i would have to put on the back of the z6. So i did. and the plugs lined up. but on the z6, there is a 2-prong sensor also on the thermostat housing that is not hooked up because there is not a plug for it on my wiring harness. Should i try to run the wires over to that sensor? would that work maybe??
