Wow, that would make what I’d like to do so much easier! Thanks for sharing.
I am assuming you only used the L and Gnd connections as @overeasy said those are the two that are used?
Just a word of caution here that those male connectors are usually too wide to use side by side into the IoTaWatt. If they are more than 11mm wide you will have a problem. You would probably need to use every other input and a thin regular plug between. That would limit you to eight (1,3,5,7,8,10,12,14). To get around i’d recommend using jacks on both ends and get some very short male-male 3.5mm cords.

I ordered this too but took longer to get here and didn’t need them anyway. Your warning is definitely valid but I got lucky and only need to extend 2 CTs for the main lines and the connectors fit side by side on the iotawatt

As I eagerly await delivery of my new iotawatt, I want to make sure that I have the wiring correct as I understand it…
I am extending 2 CTs using CAT6 cable and connecting each end to the same 3.5mm markings. Here is what I have (male end at iotawatt and female at the CTs).

Wow this is a cool idea. Here I am thinking I’d need a second iotawatt, but I’m already having a long cat6 run tomorrow (probably ~50 metres, well under the 100m limit) for a different monitoring system while we have a different upgrade trench going through the area.
I knew I could extend other CT clamps with twisted pair, for some reason I didn’t expect that to work for the iotawatt setup!
I bought these in TRRS because it was cheaper as a multi-pack, and… I had some issues with the ground pin. On the iotawatt it was the labeled ground, on my CT clamps it was V (which might be microphone? it’s not clear from the PIN out).
So I made some small wire bridges (green wire in the photo) to save me needing to remember which was which 
This is working very well even on long cable runs. The cat6 I’m using is probably 60+ metres, I did a quick test using a loopback on the end to double the cable length and the signal was still strong enough for the iotawatt to read
