GP03

It's been a long time since i've posted.....but I really need help with this one.

I want to add sirius to my 2003 S430 but the only lighter socket that I can use is the one in the ash tray. But I also need to plug in my phone charger, fm modulater for my mp3 and anything else.

So, I decided to try to clean it up and install a cigerette light 3 socket adapter in the center console under the arm rest.

The 3 socket unit has a neg (black) wire and pos (red) wire.

I fiqured I would wire the new unit to the existing cig lighter in the ashtray. I pulled the ashtray but im not sure which wire is the hot wire. I have a brown wire and 2 other wires.....one looks mostly grey with at dark (maybe blue) stripe and the other is mostly dark (mabye black) with a grey stripe....the colors arent real vivid though.

Can anyone give me some guidence on this.

Thanks

invest in a basic D/VOM and it should easily confirm ground and hot leads. can
you borrow one from neighbor or something? older style needle/analog meters
cant cost more than $30 or so

Hmmm, I may just need to run up to the Autozone and buy one.

I dont want to screw this up.

Should I be disconnecting the neg battery cable? That's what I always do when I work on my bike.

Thanks

bike and car same: when working on electical system, disconnect power
source. added consideration with M-B is that resetting and resynching
of appliances may be needed (eg seat, windows, radio code, mirrors).
so read up on that first. degree of difficulty with resetting varies with
model and year.
