Recently purchased a Pioneer DEH-150MP HU to replace the original in my 1.2 Active. Bit of a newbie I'm afraid and I have searched hundreds of sites hoping to find a solution - even followed the post on the 'guides section'. Anyway the problem is the ISO harness I am converting to, it seems that the wires don't match and I've heard that the red needs to be switched with the yellow but I'm not 100%. Also if I was to fit an ACC feed to the cigarette lighter what wire would it have to be wired to in the back of the HU?

Please help - much appreciated if someone could !

Will post photos (hopefully) to go with!

Also I apologize in advance if this is a copy of an existing thread.
