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 Tuesday at 01:32 PM Share Posted Tuesday at 01:32 PM 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.

Raven9 Posted 9 hours ago Author Share Posted 9 hours ago Your are correct, about those loosing signal, I read a few reviews on them. I ordered one for now to get me by. As far as I can tell this transmission where the speedo goes has a plug for im guessing electronic speedo. I am not a transmission guy but learning. Im local at the moment with my dump so im hoping to come up with one for this transmission in the near future.

Geoff Weeks Posted 9 hours ago Share Posted 9 hours ago Pull that plug and look inside. If there is a 16 tooth wheel in there, all you need is a pick-up and speedo head. I have or had, I'd have to look to see if I still had it, a bearing retainer that had both ports, one for gear driven cable and one for mag pick-up . It was for a Fuller. Photo of the back of the trans would help.
