All,
Thanks for the feedback and advice. :-)
I do like the idea of making it equalized across all four, and I have picked up two sets of reefer suspension parts. That will be the next project...
So after a little bit of wiring:
- Lights - (no side markers yet)

- A view of the wiring under the deck:

- The gooseneck (separate receiver to make it easier to control for the moment)
I am having some problems trying to find a good spot to locate the IR receiver for the trailer... I may have to revert to a 2nd AMO and AIR4 in the gooseneck...
It does work and later(possibly today) I will try and shoot some footage, of the loading process, and the trailer in action.
Cheers,
AP
