An antilock brake sensor does work as a timing sensor - the motor
starts right up. I won't be able to test drive it for a while but it
looks good. Now I guess I need to come up with a good way to splice
on a connector.
I currently have it installed as the "black" sensor which I think is
the one that counts flywheel teeth. I am going to put another one in
for the reference sender as soon as I get another.
