Speedometer Wiring?

Without posting a picture, I'm questioning the wiring of my speedometer. It used to work before I removed it while chasing another wiring issue under the dash... There are three wires that feed the speedometer: Red w/Black; Brown w/Red; Brown w/Red...

There are four posts on the top. As I look from the rear of the gauge from left to right, I have the following:

1. Red w/Black [Power]
2. Empty
3. Brown w/Red
4. Brown w/Red

Q: Is this correct? and, how do I differenciate between the two Brown w/Red wires? Or, does it matter cuz they do Ohms for the speedo?
