Sometimes you have to trust the location over the color but usually these were right for me.

I located the two wires of the Speedo in trans tunnle, I planned to hook those two wires to the dakota sensor of the t5, does that sound feasible? I'm a little lost.

If it's was me. I take the mustang 1995 VSS and hook the signal wire to your yellow cluster wire. Both are ground signal. Then i change the gear of the speed sensor to be more accurate on need. If you use a 1994 or 1995 ECM you need to send a VSS signal to the ECM.
