- Tested & working!
- If your engine is dying when shifted into reverse, it means you have a bad overstretched shift cable...Please test your existing switch with a multi-meter to ensure yours is not actually working before ordering.
- A tear in the shrink tubing around one of the connections, but this was pretty common on all of these that I have processed & seen because of how they oriented the soldered wires coming off of the tab connections in conjuction with how the cables were routed.
