Connecting at the Aqua Hot control board auxiliary 12 volt connection.
Linked below is a photo of where I tapped power for the electric cargo door latches I added, using the hot side (bottom) of the solenoid. I added a 6 position fuse block for future projects but you just need an inline fuse.
You probably shouldn't need to run a ground as I think you already established the existing ground is ok.
Make sure to use wire heavy enough for the application and take into account the length of the run, mine has a 25 amp fuse but yours may be different. What Entegra used is fine if you can determine the gauge.
The fun part will be routing around the wheel well. Since it will be exposed to the elements use split loom or something to protect the wire, you may also want to use tinned wire to protect against corrosion should the insulation get nicked.
Finally, before you do all that, if your setup is like mine, it may not be as difficult as you think to take a look behind that fuse block. If you take the top off the lower wiring box like I have done in the photo you'll have more wiggle room. If that's where the problem is it should be obvious.
