Hello, I was wondering if anyone has tried or already done a retrofit of a trailer brake control module/switch from a 2007-2014 gmt900 trucks to the gmt400s. I like the idea of not having the controller hanging from the bottom of the dash and the wires not being seen. I just come up with this idea today. I wanted to keep the cost to a very minimum. I have 4 empty blocks around my cargo light switch that the brake switch could go into. https://www.gmpartscenter.net/oem-parts/gm-switch-asm-trlr-brk-cont-15926102
