You can use a trailer module (TRM) from a Ford Escape for trailer lights. I have tested this myself and it works. Part Number LJ6T-19H378-AC. I plan on adding a Stealth Hitch to my Mach E and I wasn't satisfied with aftermarket light options that require you to tap brake and turn signal lights...

I created the thread to consolidate in one spot the previous good work of the other members who, through various iterations, developed these modifications and to offer further refinements to those who may do this mod in the future. Many things of value require effort. I (and probably the others...

Alright, I hooked up the spare bronco headlight switch to a multimeter with my old max defrost button installed to see what happens when you push the button. I confirm it grounds pin 10. Pics for reference.

The liftgate switch grounds pin 12, not pin 10. According to the Mach E wiring diagram, Max Defrost grounds pin 10.

You would take the wire coming from pin 10 of the headlight switch as the trigger if you are keeping the max defrost button. If you switch to the correct button in the future, you would need to add a WT1002 pin to spot 12 on the headlight switch connector and use that. The different buttons...

I stand corrected, but I can attest that wiring to the RGTM doesn't require the doors to be unlocked. Wiring to the RGTM is a fair amount of extra work, so it's down to personal preference. My personal preference is to use the stock logic of the RGTM as Ford has in their other vehicles. The...

It could be done, I think. The max defrost button triggers a different pin in the connector. Optionally, you could intercept this wire, snip it and wire the connector end to the RGTM. I would have to check the wiring diagram to see which pin the max defrost is connected to. If I find it, I'll...

Although the RGTM is on the canbus, it does not appear to get opened with a canbus message. Even the BCM triggers it with a physical wire. Some people have intercepted the wire from the BCM instead of running a wire to the tailgate, but the functionality is not correct (doors must be unlocked...

The doors can be locked, but the car must be in park. The button will both open and close the tailgate.

Using a combination of information I got from this site, Reddit and the Mach E wiring diagram I got from easymanuals.co.uk , I added the physical tailgate release button to the headlight switch cluster. This replaced the max defrost button, which I considered to be useless. At the same time I...
