No issues, good part.

### ⭐⭐⭐⭐⭐ direct replacement
*by D***R on April 2, 2019*

Harness was exactly as described, I failed with the butt connectors trying to use a propane torch instead of a heat gun and turned it into a congealed mass. My failure, not the harness, one trip to the shop and being more careful in round 2 got it licked. Harness was over a foot long so even if you need to cut back the old one or fail like I did, you still got room to work with.
