ok 2 questions really.
1 there was a aerial on the back window when i got the car. i removed it as i had no radio stations with it as it was. so where is the aerial suppose to be on a e36? i can only seem to find the 1 wire in the back of the radio

2 under the glove box i was looking at the wires and found this? what is it? should it be plugged into something?
