Kevin, call me old fashion but I'm trying to go with the wired Redarc Liberty TBC. I don't know much about the wireless controller. Could be a no brainer and I may go that way IF the wired solution fails, but I have qualms with depending on a wireless connection. Is it blue tooth with an app...
I have a "26 with basic tow package and am also looking to install a Redarc TBC. There are no wires or connector in the bundles under the dash. The missing connector used to include 4 wires:
1 - 12V constant
2 - ground
3 - brake signal
4 - brake control (the blue wire)
On my 7pin socket...
