| Vehicle / System | Tow-vehicle 7-way RV blade socket |
| Primary Use | Vehicle-side trailer-wiring function testing |

Compatibility: Designed for standard 7-way RV blade vehicle sockets. This is not a tester for a round-pin 7-way connector.
Vehicle / System Fit: Best suited for checking the tow vehicle’s connector before trailer hookup or during trailer-wiring troubleshooting.
How to Use: Plug the tester into the vehicle socket, activate the lighting or power function being tested and verify that the corresponding LED illuminates.
Performance Insight: The F7CT provides a quick check for the presence of vehicle-side signals. It can help determine whether troubleshooting should begin with the tow vehicle or the trailer.
When trailer lights stop working or a brake controller is not communicating with the trailer, first determine whether the tow vehicle is sending the necessary signal. The Brophy F7CT helps check the vehicle socket before trailer-side components are replaced.
LED indicators help verify key tow-vehicle functions before the trailer is connected.
Designed for the common RV-style blade connector used on many trailer-ready pickups, SUVs and tow vehicles.
Clearly marked BU, RT, TM, LT, BK and 12V indicators make it easier to identify the circuit being tested.
Easy to keep in a truck, service bay or toolbox for pre-tow checks and vehicle-side wiring diagnosis.
