The J1 jumper is beside the logic terminal block to the right, some times this is already in the right position but you can try it in both positions to see which works the best.

Pin numbers should be.

Pin 1=U
Pin 2=V
Pin 3=W
Pin 4=Ground
So, this needs to be corrected

Apologies that was a typo. Mostly replying from my phone.

I did correct the pin order and located the J1 jumper and tried it with no discernable difference.

This weekend I hope to test it on a higher amp circuit than the 20amp I've been testing on.
