The car I bought had an Aftermarket tach in it. I took it out and for some reason now the Speedo, Cruise and brights don't work. I know the guy who had the car before me did a strange wiring job but when I got the car the speedo worked. Only after I took the Tach out did the speedo and everything stop working. The stock speedo works just fine still. Can't seem to figure it out. Checked all fuses and they look just fine. Any suggestions? Thanks
