Could someone upload an image of the back side of the odometer circuit board for an 81 300SD, I've had to solder bridge in one place and I suspect another break in the circuit but, I'm not sure if it was meant to be that way. And, of course, if you have a schematic of the circuit that would be great too. There is another post with a great shot
HOW-TO: W126 Odometer Repair, Clock Capacitor Replace of a odo circuit but, that one is slightly different than mine, mine has an eight pin connector and is board # 992 644 520
Thanks
