stutz 712 Posted Monday at 11:33 PM Share Posted Monday at 11:33 PM I would go with a gps speedometer. I put one in my superliner. I’ll never go back to cable drive Quote Link to comment https://www.bigmacktrucks.com/topic/76158-speedometer-and-wire-for-8ll/#findComment-585709 Share on other sites More sharing options...

Geoff Weeks Posted 19 hours ago Share Posted 19 hours ago There are places that GPS looses signal, just something to be aware of. Cable driven speedo's are a pain in a commercial vehicle. Electronic speedo's driven off a tone ring on the trans tailshaft solve all of the problems. They'll run for millions of miles without a problem. Which is why they took over the truck market for speedo's when they came out. Only need 4 wires (5 if a two speed rear) and are easy to install.
