Re: Dakota Digital Dash – Speedo showing 87mph at idle
I believe the wires from the sender should be a twisted pair. If a person just runs two wires untwisted, it may allow for more interference to get into either wire. You may also have to run the pair of wires through a shielded wrap.
On the three systems I've put in I've attached the sender to the end of the original speedometer cable behind the dash. Doing it this way keeps the wiring short and keeps the sender out of the weather.
I know that not every electronic assembly can ever be 100% and last forever but I have a set of Dakota Digital gauges I put in back in the early 1990's and have worked fine with zero problems. Maybe the older stuff was made better or it was installed better but I like the ones I have.
