Morning Gents, short time reader first time poster here 
Recently bought a '03 plate TD4, great car! To go along with it I bought a Synergy 2 second hand from Ebay, couldnt let the chance pass!
Turned up this morning, all looks good but something is different from the install instructions,
That random black wire sticking out on its own from the 5 Pin connector, where does it need to go? Earth?
Thanks in advance,
Will
