Blue/Red: 12v permanent supply
Blue/Black: 12v switched supply

5-wire connector:
=================
Yellow/Green: Rear Left speaker
Yellow/Blue: Rear Left speaker
White/Blue: Rear right speaker

If it is the speakers you refer to, I have always believed it doesn\'t really matter, as long as you make sure that what you set as +ve and -ve is consistent across all the speakers.  If not you get phasing errors.

No it has the Standard Clarion ISO connector but the cars loom is not Iso standard as most cars of that era are.  I had a look in Ha<:Prds but their connectors werw DIRE and far to bulky

Anyway I have the INfo from the WWW for future reference
