Just thought i would ask on here for some help, I have searched but can't seem to find much info. I got given this for free so thaught I would try fit it this weekend. I am not very good with auto electrics! Now I need to find a feed behind my HU + ground. Does it need to be switched or permanent I am unsure, but I think switched? And can identify these wires easily to save me buying a multimeter? Thaught I would give this thing a try I was going to buy the connects2. Thanks in advance.
