Speedo signal wires
I'm try to add a speed signal to me stand alone ECU
The speedo diagram in the FSM shows two wires going to the speed sensor, but doesn't detail which is the output. What should I hook to my ecu? Orange or green? |
Trace the wires in the diagram, the speed sensor wire will feed into the ECU and the speedo. The other is probably a 5v reference.

Looked up how to wire in the dakota digital box for speedo calibration of a T56 tranny on No-Rotors and they say to use the green wire, so that's what I'll do.

Did you just connect the Y/R to G and Y/W to O? Will this make the speedo work without the ECU?

In the OEM setup, the speed sensor in the transmission connects directly to the dash cluster, not to the ECU. The dash cluster essentially duplicates the vehicle speed signal, sending a nice digital 0-5V signal to the stock ECU on pin 1M. If you still have the OEM dash installed, it will probably be easier to get the wire at the ECU connector.
In the wiring diagram, the ECU pin 1M is shown on page B-1d (Green/Red wire) and the Instrument cluster pin 3E is shown on pin C-1a (Green/Red wire). |
