Owning a Corvette in the UK can throw up the odd challenge. Today’s problem centers on the factory radio unit. The US spec unit is notorious for not picking up UK radio stations. The Euro spec radio works fine but generally comes with the 12 changer CD which, of course, is not factory installed on the Z06.

I have acquired a factory Euro radio and 12 changer which I want to fit into my 2003 Z06. Am I correct in saying the following?

1. The factory did not install the body wiring harness to the CD changer when it was not required.
2. In order to connect up the 12 changer, a Cor-Har wiring harness is needed which runs from the CD changer to the passenger foot well fuse box.
3. The Cor-Har then plugs into 3-way and 4-way connectors in the fuse box area.

Here is my problem – I am having difficulty in locating the 3-way and 4- way connectors in the fuse box area - my instructions say that one is taped to the wiring harness and the other is clipped to the metal bracket above the fuse box. Well, I’ve looked and can’t see them and I’m reluctant to poke around too much in that area for fear of disturbing something crucial.

Can anyone tell me exactly where these connectors are? If anyone could give me a clue to the colours of the wiring that could help me trace them. Photos would be even better.

Many thanks
