Hello

I've just found a 2004 D2b version of the Sirius OEM receiver, to install into my C230 Coupe.

The pre-wire was not available on the 2004 Coupe as it was in the 4door and wagon models.

I can buy form the dealer a harness that is for the factory HU 6-CD changer and Sirius. The cost is over $200.00 for a harness most of which I already have in place and don't want to spend this much to use the Sirius portion of the harness.

What I'm looking for is from left to right what is the placement of the 12v, Ground, and Wakeup wires, the Sirius Receiver has three male pins for the power socket. The other thing I need to know is what are the colors of the wires? To verify if the 12v is on 100% of the time or ACC switched, and if one is blue to verify if the third wire is wake up which I'm almot 100% sure of but can't find any information on this.

I can make a custom harness if I know which pin accepts the correct wire, I don't want to fry the receiver by pluging the 12v into the wakeup...

And if there is a part number to build the plug and female pins even better.

Thanks for any help here....
