I have the same issue. I have cabinets that I want to jump between. If these are not available or I can't find what I need I think I will take these back to the store since this product is to expensive to throw sections away that cannot be adapted to smaller lengths. 

@Carl 

Has there been any progress? I've found multiple threads going back years that just die off as soon as 'Kasa' says they'll look into it. The custom pins do make it very difficult for someone with exp to make look clean.  Could we at least find out who makes these connectors so we can try to source them ourselves?

I have over $600 invested in my whole home in TP Link Kasa bulbs, plugs and switches.  I have waited well over a year to upgrade my kitchen cabinet over and under lighting simply bc there are no adapters or wire extensions offered for this set.  An LED strip set without wire extensions(not just light extensions) or adapters is unsellable in my opinion.  Unfortunately if none are made for this set,  I will be switching out all of my TP-Link products to another brand which offers these adapters and wire extensions. Which I'm super shocked TP-link STILL doesn't offer when everyone else does!

would lthis work?

@RyanEverhart789 - Possibly, I'm not too sure.

I have a lot invested in tp-Link components also, which is why I wanted to use their light strip in order to preserve my smart home ecosystem.  With a little engineering and cutting I was able to add extension cables and connect multiple strips through cabinets and around corners.  No soldering was required. All of the lighting effects continue to work as designed.

These were the connectors I used from Amazon:

I used one KL430 6-foot light strip, plus two 3-foot extensions.  I cut each of the 3-foot extensions in half since I needed two locations where I was adding the connectors and extension wires; be sure to cut ONLY where you see the 4 silver pins joining the light strip together in the center, then strip the adhesive off the back of the light strip where you cut in order to expose the 4 copper terminals.  Since the plastic connectors are 10mm, and the light strip is 12mm, you'll need to cut about 1mm off of each side of the cut strip in order to make it fit into the connecter.  Be careful not to cut into or damage the copper terminals or any of the small electrical components inside the light strip.

Follow the standard instructions for setting up the main light strip and the extensions: plug in the main light strip only (with no extensions attached), follow the instructions in the app to join the light strip to your network, unplug the main light strip, connect the extensions to the main light strip, then plug it back in.  If you have problems, you may need to delete the light strip from the app, reset it, and start over with the setup process...it can be finicky, especially if you're testing the connections and jumpers as you go through the process of making sure each of them works.

Hope that helps.
