Why does my '93 190E 2.6 have a wiring harness and electrical connection at the top of the rear differential? Can't imagine what it might be for.

Thank you,

Jack

ASR or ASD connection?

Don't have either of those options but your input is appreciated.

ABS sensor inside differential is the winning answer.
