2003 Mercedes Benz C280 AIR BAG /OILCHANGE RESET CONNECTOR

PLEASE DESCRIBE FOR ME THE LOCATION OF THE
CONNECTOR TO RESET THE SRS AND THE OIL CHANGE. MY CAR IS A C 240.

2 WEEKS AGO A DIME FELL INTO THE CIGARETTE
LITTER TERMINAL AND BLOW THE FUSE, WHEN I TRY TO CHANGE THE FUSE I PULL THE SRS FUSE AND DISACTIVED THE SYSTEM

I KNOW THERE IS A RESET TOOL THAT I LL BE ABLE
TO GET AFTERMARKET BUT, NEED TO FIND THE SIZE
OF DE CONNECTOR.

I DO MOST OF THE MAINTENANCE OF MY VEHICLES AND I HAVE A GOOD MECHANICAL KNOWLODGE.
SOME INFO ABOUT THE RESET TOOL WILL BE A GOOD HELP AS WELL.

THANKS FOR YOUR HELP ON THIS MATTER
