My can is 560SEL 1989. After changing injectors, spark plugs/wires and some other parts such as fuel accumulator, after that I noticed two problems:

1. The car will not start until I reverse the EHA wires in the opposite position. If the car was hot it will start but rough.
2. The trip cluster that indicates the current fuel consumption is reversed. That means when I accelerate it indicates low fuel consumption and when I release the fuel pedal it indicates high fuel consumption.

I tried my best on that car but it was useless. I don't remember that I reversed any wires. Have anyone faced such problem before?

This is a real mystery at leat for me.
