My sister brought her '89-245 over stating that the speedometer-odometer wasn't working after gas fillup and reset of odometer.

I found wires hanging in the rear. Broken off from plug that goes into sensor. Removed plug, not enough wiring left to determine color. Rewired and guessed at blk and blu wire positions in plug. (50/50 chance of getting it right/wrong). Diagram in Haynes doesn't help. Since rear on stands, started car and put into drive. Speedo worked. Wrapped up.

But when I test drove, the speedo worked but the odo didn't. So flipped wires in plug. Speedo works but odo still doesn't. So did I damage the odo by having wires reversed initially?

Sister needs car so returning as is until car is available.
