How do I know which of the above parts does my engine belong to? Where is the number located on my car? I have a 1992 2.6 190E.

Part: A/C ACC Temp Sensor
To which engine range does the vehicle belong?
10-005709-
12-008051-

For example if I look up a/c acc temp sensor on benz bin I get to different part #.

I called the dealer. I gave them my vin number
and they told me it is: 12-0061686.

So does this mean it belongs to: 12-008051?

thanks in advance,
Joseph
