However, I've noticed that there is a plug that attaches to a sensor on top of the throttle body which is not connected to the main engine loom. It comes directly out of the car side of the E36 loom. What do I need to do with this?
It's the one shown connected in the picture below.

The other thing i've noticed is that I had to remove two cables from the throttle body. The lower one looks like the throttle cable. What does the other smaller one do? Sorry, I forgot to take a picture of it so let me know if that doesn't make sense.
Thanks
