If you go to the product description page for the Hopkins Tail Light Isolating Diode System, part # 38955 and scroll down to the bottom of the page (use the provided link) you will see 4 install diagrams.

The wiring method used will depend on the way the tail light circuits on your RV are wired. The lights can be wired in one of two different ways. If your RV uses what we call a combined system, the brake light and turn signals are combined into a single circuit, using a singe bulb on each side for both the brake light and turn signals. If your RV has a separate amber bulb for the turn signals, it is considered a combined system.

From my research, I have found that the Fiesta uses a combined system. If the RV uses a combined system, use the first diagram. If the RV uses a separate system, use the third diagram. If the RV is a separate system that uses a separate bulb for the turn signals, you will also need a vehicle to vehicle converter like the Roadmaster Brite-Lite Converter, part # RM-732.

I have provided a link to an install video showing the diode kit being installed on a similar vehicle. The Honda Fit shown actually has a separate tail light system, but the diodes are being installed so that the tail lights function like they would on a vehicle with a combined system. What is shown in the video is very similar to the procedure you would use to install the diodes on your Fiesta.

I have also linked you to some other Flat Towing FAQ articles that you might find helpful.
