IBC brake control

[xps800doo]

so i have a 15 2500 and it works fine with a eoh boat trailer. just picked up a 14 2500 also and i knew the ibc would not work and planned to get the adaptor module(https://www.etrailer.com/Accessories-and-Parts/Dexter-Axle/DX35FR.html)

 

first off how do these systems work... what is this module that makes it work on the pre 15's 

 

second if i put this on the trailer what hapens if i pull it with my 15 that already works without it??
