Dakota Digital in Classic Builds for C10, Camaro, and Chevelle
If you are planning a digital gauge upgrade for a C10, a first generation Camaro, or a late sixties to early seventies Chevelle, this guide will help you pick the right Dakota Digital series, wire it cleanly, and avoid the problems people run into on Reddit and forums.
HDX vs RTX vs VHX
HDX gives the most control over colors and data. It suits pro touring builds that want a modern feel with a clear analog layout.
RTX keeps a factory look with a hidden info window. If you want stock appearing faces with smart internals this is the safest pick for restorations.
VHX is the dependable value choice with a clean analog look and a center info screen. It is the most budget friendly of the three.
Model specific picks
Chevy C10 from 1967 to 1972
Best fit RTX if you want a stock leaning interior that still shows modern data. HDX if you prefer a modern look with color control. VHX for a classic vibe on a tighter budget.
Install notes Use a solid chassis ground near the dash and run a dedicated ground to the cluster. Calibrate fuel level to the sender ohm range. Common ranges are GM zero to ninety ohms and aftermarket universal two hundred forty to thirty three ohms. Match the sender during setup and do the two point calibration.
Speed source Use a vehicle speed sensor from the transmission or add a GPS module when a sensor is not available. For an LS swap you can feed speed and other data from the engine control module with a CAN bus or OBD II interface to simplify wiring.
Camaro from 1967 to 1969
Best fit RTX for a stock leaning interior. HDX for a custom restomod with color matched lighting. VHX for a simple clear readout.
Install notes If you moved to LED exterior bulbs use an electronic flasher and confirm the turn indicator leads at the cluster. Tie the dimmer input to the headlight dimmer circuit so the cluster follows night brightness. On console tach cars plan the RPM signal early. A CAN module or a tach output from the ignition box or ECM keeps the signal clean.

Chevelle from 1968 to 1972
Best fit RTX for sleeper restorations. HDX for pro touring cars. VHX when you want reliable and simple.
Install notes Give the cluster a clean switched twelve volt source that is not shared with blower or wiper loads. Star ground the cluster radio and any USB chargers to reduce noise. Calibrate fuel empty and full with the tank near one quarter and then topped off to dial in the curve.
Wiring that just works
- Battery and switched power Run a fused constant twelve volt and a clean keyed twelve volt. Avoid sharing with blower or headlights.
- Grounds Use a star ground on bare metal. Paint and seam sealer create voltage drop.
- Speed input A vehicle speed sensor is ideal. GPS is fine for cruisers. For an LS swap use a CAN or OBD II module to bring speed into the cluster.
- Tach input Use ECM tach out or ignition box tach out. If you must use coil negative add the proper interface.
- Fuel level Match the sender ohm range. GM is often zero to ninety ohms. Aftermarket universal is often two hundred forty to thirty three ohms. Ford classic is seventy three to ten ohms. Calibrate in setup.
- Lighting and dimmer Tie the dimmer input to the dash dimmer so night brightness is comfortable.
- Indicators With LED bulbs use an electronic flasher and verify indicator polarity.
- Expansion Add BIM and CAN modules for oil temperature transmission temperature or gear position without extra standalone gauges.
Quick fixes to common issues
- Speed jumps or drops to zero Check grounds and power quality first. If you use GPS mount it with a clear view of the sky. If you use a vehicle speed sensor confirm the signal and make sure the interface is set correctly.
- Fuel reads wrong Sender ohm mismatch or poor ground. Do the two point calibration in the setup menu.
- Dimmer does nothing Verify the dimmer lead is on the correct circuit and not a headlight feed.
- Tach is noisy Use a clean tach output from your ECM or ignition. Add a signal interface if you tapped coil negative.
- Turn indicators stuck or hyper flash Use an electronic flasher with LED bulbs and check indicator pin polarity.
FAQ
Which series should I pick for a C10
RTX if you want a stock look that hides modern info. HDX if you want modern styling and color control. VHX if you want a clean classic look and strong value.
Should I use GPS or a vehicle speed sensor
A vehicle speed sensor is most consistent. GPS works for cruisers and simple installs. An LS swap can feed speed RPM and coolant over CAN or OBD II with the right module.
Will Dakota Digital work with an LS swap ECM
Yes. With a CAN module or OBD II interface the cluster can read speed RPM coolant and more without extra senders.
What fuel sender ohms do I select
Match the tank sender. GM is often zero to ninety ohms. Ford classic is seventy three to ten ohms. Many universal senders are two hundred forty to thirty three ohms.
My turn signals or high beam indicators do not work as expected
Use an electronic flasher with LED bulbs confirm indicator leads and improve dash grounds.
Can I dim the cluster with the factory headlight knob
Yes. Connect the dimmer input to the dash dimmer circuit so the cluster follows your night brightness setting.
