For whatever reason$, Kidde changed up the wiring harnesses and connectors on their newer hardwired detectors so if you are replacing existing hardwire Kidde detectors that have reached end of life, you either need to re-wire them with the new stuff (provided with the detectors) or make it super-easy on yourself by buying one of these adapters for each detector you are replacing. These cost less than $5 bucks at h*me d*pot but good luck finding them in stock. for a ~55% premium (I paid $7.77 per) I had them from Amazon in less than 2 days. Unless you have absolutely no idea what you're doing (no judgment here!), changing out the wiring harness DIY is a very doable job, but unless you're extremely quick the time savings these provided were well worth $7.77 a pop. And if you don't know what you're doing with electricity (again, no judgement here) you'll essentially eliminate any risk of shock/electrocution using these in lieu of rewiring, again well worth it at under $8 per detector. It took me about a minute to swap out each detector using these adaptors and I didn't have to worry about screwing up...to remove the old harness and rewire the new probably would have taken me about 10 minutes per detector conservatively, not counting cussing at dropped tools and wiring nuts, the annoyance of having to cut power for a while, etc. If you can afford it and/or value your time at more than 50 cents per minute or so, save yourself the headache and buy these. And if you are considering hiring an electrician to wire some new Kidde detectors for you to replace your old ones, this will save you a ton of money and I promise it's easy enough to do yourself.Tested all 7 smoke detectors in my home after installing with these adapters and they worked as expected including interconnection of alarms. Knocked out a job I had been putting off for 2 weeks in less than 20 minutes and enjoyed the rest of the weekend with no chirping (both from the old alarms or from other members of my household annoyed I hadn't replaced them yet).

For the price cant beat these . as simple as plug and play can be. saves the time of disconnecting old & rewiring new ac connection when replacing expired kidde units- swapped 6 new detectors

If you have older wiring, this adapter makes it easy to connect to newer Kidde alarms. At $5, it's a very inexpensive way to update your alarms. It was very easy to install and works well with the new alarm.

This adapter worked perfectly to substitute the new model detector for the old unit.

I was a little disappointed that the new smoke detectors used a different hook up. I dreaded turning off the electric to replace them. These worked like a charm. Quickly switched the detectors without turning off the electric. I have to wonder if the change of connectors was just a way for Kidde to increase profits.

The adapter works great with our 10-year oldKidde detector wiring and was easy breezy to install.
