What wire behind the dash is responsible for the odometer? 1987, 245, Manual
thanks, sammy

 

the odometer is mechanically part of the speedometer, the speedometer is connected to the rear axle speed sensor via connector 233 pin 1 and 2 (blue and black, usually). connector 233 is the right angle 3 pin connector. pin 2 is grounded. pin 3 powers the speedo/odometer assembly, is red/black (usually), connected to the ignition switch pin 15.

 

Thank you, Sir.
