Dakota Digital RTX with Stock Harness

[DeezNCSU]

I've combed through all the Dakota Digital posts and most seem to revolve around installation with aftermarket harnesses. I bought one and plan to install it soon, but I have the OEM harness so I wanted to see how others have wired a few of the inputs to the control box. I'm comfortable with wiring, just not overly familiar with the stock harness. I have a '68 model with a new Blueprint 302. Here are the inputs I'm looking for direction/confirmation on...

1) Tachometer -
2) 12V+ Constant - yellow?
3) 12V+ Ignition/Switched - black-green (#297) from ignition switch?
4) Dim
5) High Beams - green/black stripe?
6) Left Blinker - green/white stripe?
7) Right Blinker - white/blue stripe?
8) Fuel - orange?
9) Ground

Bump on this - hoping to get some feedback before I try to tackle the installation tomorrow or Saturday.

The colors you have listed match with the diagram (Steve’s) I have for a 72. It shows a red/yellow from the lamp (light) switch to the dimmer switch that would work for the dim function if it needs 12v to dim the display when the lights are turned on. Im not aware of tach wiring unless the later models added it. My 72 had an aftermarket tach when I bought it in 73 and it used a box mounted on the fender well with a battery and some electronics that connected to the primary circuit of the ignition coil and the tach mounted on the steering column (4 wires). With the Dakota it will probably depend on what kind of ignition the blueprint has. ???
