1. Remove the cover plate, control handle, the clip that secures the cable unit, and unattach the old cable.
2. Just remember how the old cable was attached and reverse the process. The replacement cable was a perfect fit.
3. The installation process would have been much quicker had I not lost the clip that secures the cable unit and had to fabricate one.

Not the part I ordered

I was not satisfied with my order because I was shipped the wrong part. They shipped me a spring part for my lawn mower instead of this nut for my bolt. Was not happy at all.
