Aftermarket Radio install - HELP!!

Hello everyone,

I'll intro myself in the appropriate section later, for now I have an important question.

I'm trying to install a Kenwood head unit in a 2002 E430. I've gotten as far as removing the stock radio and discovering what looks to be a fiber optic cable and an extra harness that doesn't match up to the harness I ordered. I should mention this is a Bose system without Navigation.

Another issue is I can't seem to find a 12v accessory wire. The harness is slightly different from what it "should" be in that the wires are in different configurations. That's an easy fix - but where do I get acc 12v from?

If these topics have already been covered, I apologize. Search has lead me nowhere as of yet and I'm just trying to get this thing done. I can build a harness if necessary but I need some direction first!

Just another thought - Does anyone think I could use a relay and that low voltage signal to send 12v to the accessory lead on the radio? I would just tap the constant 12v and send it through a relay tripped by the one lead that fires 0.5 volts.
You could explain which wire is this one that fires 0.5 volts, and when does it do this? Are you going to purchase an 0.5 V relay?

I guess you've got the after market radio installation instructions. You should find the OEM MB radio connector descriptions from the forum (or google) and the switched voltage you can get from your cigarette lighter (at the correct fuse position). That should be all.
