Did you look at the electrical diagrams?
yes - but the ones in the FSM doesnt anywhere show the connection to the speedo in the 'gauges' schematic #120. in schematic #111 they talk about a 'vehicle speed sensor'. im assuming this the name for the electrical connection on the back of the speedo and is part of the cruise system.

Correction: the wire that was in my 'vehicle speed sensor' slot is one wire red, the other wire is gray/purple. it comes up from a big run of wires below the ignition switch. it *looks* like it being mis run up to the back of the cluster.

So, it only makes sense that the wire i have pcitured in the first thread IS indeed the wire that should go to the back of the speedo and the wire that *was* in the back of my speedo is the mystery wire.

i have further confirmed this - when i plug the red/grey wire into the speedo my off current consumption on the car goes from 4ma to 18ma. thats not right. when i plug in the other one it is at about 4-6ma. thats right.

so the mystery continues. ill take some more pictures and post them.

thanks for all of the help so far...
