Unhappy Please HELP!!!! 300E Wire connection

My last thread didnt make it , Ill try again does anyone know the color code to the round wire connector, the one behind the fuel and temp gauge in a 300e? I was going to replace a bulb and in removing the connection ( the one with 15- 16 wires connected to it) the connector separated and I had 6 to 8 wires pop out of it, I tried to carefully put them back in their respective holes but I didnt get it right, I have removed the cluster several time in the past and this never happened before.
Is there anyone who can direct me to a photo or even a wiring diagram of this connector, or possibly someone may know the color sequence to the numbered holes where these wires go.
Please someone help !!!!!!!

Thanks for everyones help.!

just as a side note I was able to get that information off from the ALLDATA web site within about a minute. I encourage anyone and everyone to see what they offer because I love it and have found the information to be excellent and accurate. Much easier to navigate than the benz factory CD's (in my opinion). Everything from trouble codes to changing your oil, good stuff!!!
