CURT 51200 Echo In-Line is a proportional Bluetooth trailer brake controller for one to four trailer axles (two to eight electric brakes). This version mounts near the rear of the tow vehicle, out of sight, and plugs in-line between the existing factory USCAR wiring connector and the vehicle's 7-way RV blade trailer socket using its supplied harness. Unlike Echo Mobile, it does not sit between the exterior trailer and vehicle plugs; unlike Echo Under-Dash, it is not mounted inside the cab. The sealed module uses triple-axis motion sensing and the CURT Echo smartphone app for settings and status. It continues with the last programmed brake settings if Bluetooth is lost. Confirm that the vehicle has the required factory USCAR connection behind its seven-way socket; do not assume all 7-way setups use USCAR.
