Well, it is a bit hard to install in terms of the risk due to how short and fragile some of the wires are. But, beyond that, even after setting everything up the speedo would keep "flickering". So, say I am driving 55 mph, every so often the speedo would jump all over and stuff. This rendered the cruise control useless as the truck would suddenly try to floor it all the time.

I actually called dakota who pretty much offered no advice. Said what I described was "not possible".

I got home, removed it all and did my best to mend the wires (which is thankfully holding to this day). Returned the device and lost a good bit of money selling the larger tires and buying normal size ones again.

I was so freaked out about the speedo never working right again...

Oh wow, that is good to know! Thanks for sharing your experience. I've had a similarly bad experiences messing with the wires on another vehicle so I know what that's like. Glad to hear to hear you at least got it working in it's stock configuration.

Funny you mention 55mph. That is the only speed where my Dakota Digital calibrator has a little glitch. Rock solid otherwise.

I've rewired a few Toyotas over the years, so the wiring side of it didn't seem particularly difficult for me.
