Yeah, i have the wires(i believe they are green and purple..cant remember) from the new harness. i just need to splice them into the wires of the sensor on the t-case. So now that the computer is getting the signal, is the signal the right pulse for the computer? also do you know what color wire is the right one to wire for the gauge?

the wire that goes to the speedo in my cluster, i know the speedo wire from the computer thats running the motor/tranny(the 2004 computer). Chilton manuals only give you a hand full of wires in the schematic.
