Did you do all of the splicing right by the back of the speedo, then leave the yellow box behind it in the back of the dash? (Their instructions indicate to do it down by the sensor pick-up at the trans, then run a cable all the way up to behind the dash, but this seems silly).
Any photos for us that are electrically challenged would really be helpful.
Thanks again...

If you look at this schematic you will see the speedo at the right side.
Note the colors and where the wires come and go to.
The red/black stripe comes from the fuse box.
The browns are ground
The red/browns(2) come from the speed sensor, one comes from the sender and creates the pulses and the other one is the "ground" for the circuit. Neither wire carries any significant voltage or amperage so switching them around won't do anything other than cause your speedo to not work, until you switch them back.
The power is required for both the speedo and yellowbox, hence the 1 into 2 pigtail.
The ground is required for both the speedo and yellow box as well.
It's actually easier than it sounds. The reason I did pigtails and auto spade connectors was to eliminate "splicing"
The pigtails allow plug and play.
