How to Wire a 2015 Ford Edge SEL to be Dinghy Towed
Question:
I recently purchased the RM-154 kit and cannot figure out how to get it wired correctly. I can get the LED side marker taillights to work but cannot get the rear LED taillights to work with the diodes.

Dinghy wiring the 2015 Ford Edge SEL model is quite a bit different than normal diode wiring because Ford combined the stop, turn and taillight signal on the same wire that goes to the rear facing LEDs in the taillight.
To make the # RM-154 kit diodes work properly you will need 2 resistors rated for 50 ohms and 10 watts for LED tail lights or 2 rated for 5 ohms and 10 watts for incandescent tail lights, available from a local electronics supply store. You will also need to wire the diodes differently to get the LED taillights to work properly. I have attached a diagram showing how to wire in the resistors and the diodes.
We did a flat tow setup on a 2015 Ford Edge SEL here and found that the correct wire to splice into was the darker brown wire which is most likely the same wire you used that only illuminated the side marker lights in the rear taillight housing. Using this new diagram you will get the rear taillights to work properly.
