Yes.

You get about 2-3' of XDCR cable as close to the head/connector as possible and pass it thru with 8-12 loops (more is usually better) and put the cable tray back together - though testing it with different numbers of passes thru is a good idea.

I staked 2 of them for more filtering and it works good on a lot of installations!

This is probably less expensive if you choose economy shipping, and I would recommend you try 2 instead of just one.
Clear coat them (prior)and I used cable ties & quality electrical tape to "bundle them".
