Cyberdyne speedo and stock sender? 5S-FE

[usagie99]

first of all, i do not actually own an MR-2, i just have a 5S-FE that came out of one jammed in an 1987 Toyota corolla.i just recently finished up getting the car to run and drive the way i wanted, though i cannot tell how fast i am going.(an excuse for the police??? ) originally the corolla had a mechanical speedometer gauge that was partially broken(stopped reading after 65mph) so when i went and put the 5S-FE in i figured i would buy an aftermarket electronic gauge and hook it up to the stock speed sender in the transaxle.

my problem is i cannot find any information on the speed sender in my MR-2 fsn and i need to know how to hook it up to a cyberdyne speedometer. the stock sender is of three pin design, but i cannot find a wiring diagram on it. the cyberdyne gauge has a white wire coming out of it which supposedly connects to the sender in some way(the cyberdyne instructions are incredibly vague)

any help would be greatly appreciated!

edit: i found info on the pins on the speedometer sender by searching lotus forums and now my speedo works great.
