Dakota Digital wiring?

dodge68charger · Aug 18, 2025

Hey guys wiring up a dakota digital
VHX in my 1970 charger. I did the RTX in my superbee last year.

I drew a blank on 2 of the circuits

Where should I tie in to get lights when i turn on the headlights?
-Tap into the Rear tail light wiring circuit?
-Tie into one of the Orange wire bulbs in the dash?

Wheres a good spot to get a 12v ignition source for the park brake light?

Anywhere close i can tap into?

Orange is instrument cluster / marker lights to DIM (+) input.
Might also need Hi Beam light which should be on original cluster
Park brake light is normally a ground. Does the VHX require a positive input?
Could use the +12 volts powering the dash, and a small relay to reverse the polarity if you need to for the park brake light.
I looked at the instructions and the brake warning input is a (-) negative / ground input so the original wire going to the dash warning light should work for the input.

Thank you. I’ll use an orange wire to the ‘ Dim ‘ port on the control box.

The parking brake says it requires a 12v source and ground which was different than the ‘ RTX ‘

I will look at the parking brake light plug on the 70 charger. It looked like it had 2 wires going to it. Otherwise I can use the 12v + black wire to the dash.

Do I still need to reverse polarity?

I see, that is just a separate light indicator for the original dash location and not part of the digital dash. The +12 volt wire is just to supply power to one side of the bulb from Accessory Key On power, and the brake warning switch side is as stock. The Accessory Key On power should be the same power that powers up the rest of the dash.

Here is my experience with the RTX brake warning light wiring. See post #34.
