Dashboard Wiring Upgrade - A Dash Of Class

For the proper operation of the electrical system, we installed a new ignition switch from LMC Truck. They can also supply a new plug to replace damaged originals.

While we had the dash apart, we checked a few other things. Over the years, the fuel gauge would only read about ¾ even when full. The problem turned out to be a damaged fuel selector switch. We got a replacement from LMC.

This is the plug on the heater and A/C blower motor switch. High resistance in the switch had created enough heat to damage the plug.

We ordered a new fan switch from LMC but forgot to order a plug, so we cut the damaged wires and added individual connectors.

The fan motor and gas tank switches mount to the heater control assembly. Replacing them made the gas gauge function properly and the fan motor to run noticeably faster.

For transmissions with a cable drive speedometer, Dakota Digital offers this electronic conversion.

Dakota Digital’s instruments require specific senders and cables. This is the oil pressures sender, which has three contacts. The cable includes a sheath over the wires to prevent interference that would result in inaccurate readings.

Same with the temperature gauge, a Dakota Digital sender is the only one that will work. Both senders include weather-tight connectors.

Along with the senders are a variety of adapters.
