Turn signal/ABS question
 

Hi guys and gals-
Strange problem on my 1990 300sel. When I turn on my right turn signal, my ABS light on the dash comes on. It stays on for 5-10 minutes then goes out.
Also, my right t/s flashes faster than my left. (maybe twice as fast.) The ABS light does not come on when I use my left t/s, and not when I use the brakes. Brakes work fine and pads are good all the way around. If anyone has a schematic, is there any connection between the right side turn signals and the ABS system or dash light?

Sounds more like a printed circuit board on the cluster to me,
