I replaced mine early this year with the Sierra International push to choke unit and it works fantastically. Not sure if that's the one you got from Overtons but they are pretty simple mechanisms and shouldn't fail easily if they're new.
This. After I left my keys on the truck bumper one day, I went with a Sierra. Never a problem from either. The original was 18 years old. Worked great. Just, like Gary said, shrink the connections. On mine, I didn't have to cut and splice. I cleaned the contacts with 600 grit paper and tightened them down and shrinked over them.
Good as new.
