I recently bought and installed the aftermarket Sirius kit from TSS Radio. It plugs into the CD Changer harness in the boot. Issue: Ground Loop Noise. I have purchased an in-line power filter but need to know which wire to cut in the harness (I need the power wire). I do not have a probe to test the pinouts. Help? oh, '04 Cooper-S Hard top. Thanks!!

 

The constant power to the Cd Changer is:

"Wire 2 on the 3 wire connector" AKA: The middle one.

Hope this helps others...
