I've just bought a Kenwood KDC 405UB 8 plate C3. I also got the adaptor which goes between the car's wiring and the new stereo. I gather the red (live) wire had to be cut and joined to the red wire on the adaptor as the red wire was loose on the adaptor, so i did this. everything else is as it was out the box. The problem in the stereo has no life whatsoever. Have I totally messed up? Any help would be apreciated. Thanks in advance. :oops:

Hi Robbo77

You can connect the radio straight up without changing anything (pin 7 goes to pin 7 and pin 4 goes to pin 4) and the radio will work for testing the unit. It will drain the battery and not remember the programming so its not to be left like this. Its only to see what still works.

Swapping the pin 4 and pin 7 on the power plug over puts the stereo power back under computer control to save draining the car battery and then shutting down the central locking and alarm system..........

Not knowing which adaptor you have (as some are generic ISO and some are specific to the Citroen C3) I can't say what colour the wires are, or if they need changing.

If you have a generic ISO connector on one end and a Kenwood plug on the other, try swapping over the wire that goes to pin 4 on the ISO plug with the one that goes to pin 7 on the ISO plug (and vice-versa).

Colours would probably be yellow and red, but you must identify the wires by the pin number!

there is a picture of the ISO connectors and their numbers here: ... nout.shtml

the fuses in the glovebox guide is here: ... -t153.html
