I replaced the shift gear selector and installed a new gear shift assembly in my 1997 XLT. After I put everything back together, none of my guages work. The speedometer, tach, gas guage, oil guage, battery guage, all stopped working. I checked the maxi fuse under the hood, and it is still good. I checked fuse #15, and it appears to be good. I took the dash apart again and made sure the three connections were in tight. They are. Anybody have any ideas?
