To start with i have more pin sockets than the one shown on http://www.audi-sport.net/vb/showthread.php?t=23093&highlight=bose+amp (by andy amc) . I have a standard current tester. I have worked out which is the remote. and my live and ground are sorted...just a little confused as to which im ment to tap in for the lower level input...obviously i need it to have the correct pallarities(spelling bad,sorry). Anyone got any ideas which they are...there is a picture on my profile if you thinks you could help....many thanks in advance...
