This is the problem. 1999 ford ranger 3.0, change gauge console because old owner but new face covers on and gauges were not reading properly. Found used console from a 1999 ford ranger and the odm. was only of by about 150 miles. Switched gauge console, but also switch removable circuit card at back of console. I beleive the tach is working and mph is working correctly also gas guage. But odm does not turn, and I don't think the temp,oil,or amp are working. Question should I have left the removable cards alone, or is something else I need to do. Any Answers Thanks
