after taking this plastic cover off, you cans ee the circuitry, and this is how i fished the 2 wires up through the board and through the small hole and solder the wires into place. BE CAREFUL not to get solder connecting into the other circuit paths(the copper color lines on the board). if you do this you are basically connecting the paths, and may mess up something. i would suggest solding on some cardboard for practice if this is your first time.

then replace of course in reverse order.

So I re-soldered my original resistors Paths and pads all looked good yet . and now my odometer fades in and out randomly Also I think the miles are off, The previous owner was pretty sure it would be close to 200K and it is reading 075241

Fading is either the resistor is bad or solder connection somewhere either at the joint or copper on the board isnt transmitting. Id just guess the resistor.
