I'm looking to attempt this as well. With this break controller and the oem harness for 7 way, did you still have to take it to the dealer to have it reprogrammed? Would you mind putting the link to the OEM 7 way harness on here or the part number. I have a 2015 Discovery sport 5 seater. Thank you!Found the brake controller plug socket under the dash. Connected a Tekonsha brake controller (Prodigy P2) using the Tekonsha Ford brake control harness (3035-P) which plugged right into the vehicle's brake controller plug/socket. Pretty straightforward job once you find the brake controller plug socket under the dash. Have also got the factory OEM harness for the 7 pin electrics which is simple plug and play into the connector located inside the boot floor (above the spare wheel).
