Hi all, I am trying to wire up a Kenwood H/U, the KDC-U449 model but am having troubles sorting out the wiring. I have looked at the first post on here but still not sure where everything goes. I cut off the plug from the back of the original H/U and was hoping to solder the wires onto this and re use the plug but when I connect it there is no power. On the plug I have the following Yellow Grey Pink Tan Lt Blue Lt green Black with white tracer. The instructions for the Kenwood unit (no problems with the speaker wiring all understood there) but the book states Red - ignition wire, Yellow - battery wire and the black I can work out. Is anyone able to help with what I am doing wrong. Nathan ---------- Post added 05-08-13 at 17:26 ---------- All sorted the yellow had to be splice with the red onto the yellow from the original H/U

The way you have connected it (yellow and red) joined together you will realise that you wont be able to store any radio stations or settings in the hu because your cutting the power off completely everytime u turn the key off
