Three quickies: What pin location hole does the Tach wire go in to when swapping a 4Runner gauge cluster into a 85 pickup? (The write up I found is good, but I can't open the photos to see the "red arrow")

What bulb locations are left empty on the 4Runner cluster? Both clusters have some empties. I'm swapping LEDs into the 4Runner one while it's out.

Is it possible to swap odometers out? My 85 pickup has 78k miles- the 4Runner cluster shows 198k+. If I'm not going to screw it up I'd like to swap.

PM at KRCaddis@thegrid.net or thru facebook please/
