So my speedo doesn't work and when I bought the truck there was a new cable sitting on the passanger seat. Being the proactive young man I am I put 2 and 2 together gathered I needed to swap it out. The Haynes manual I have gives no pictures and just says, "Take off old cable, put new one on." Do I have to take the dash apart and pull the speedo gauge? What about how it is looped through the frame? Any help, tips and/or tricks would be appreciated.
