Bought this to replace a similar model that came with my house. Even though the old disposal was a different model, the connecters were the same. Wired the old cord to the new model, used a small car jack to hold it in place as I installed it (makes it even easier). Installed in 30 minutes. Hand tightened all the connecters - no leaks. Runs even quieter than my old mode. Great product for a great price.
