One of the big issues is with the type of brake system you are going to use in the tow vehicle. The 2.3 engine uses a vacuum booster just like most normal vehicles. The 2.7 engine uses a electronic brake boost system (EBB). I used a BrakeBuddy Stealth system in my Jeep which had a vacuum pump...
I wonder if the electric brake boost is active when the Bronco is placed the tow mode. Will be on the phone first thing Tuesday. If this is true your Air Force One and my Brake Buddy Stealth will both work fine just don't have to hook up the vacuum generator to a brake vacuum boost.
Any updates? For what it is worth the D-Ring brackets on the Modular bumper are 1.1145 thick. I don't have a problem opening up the BX88357 by .126" there is still lots of metal left. Just wish I could get a good answer from Ford about the D-Ring brackets . This is what the owns manual saids...
Here is a cad picture of the tow module that is included in the tow package. Look at some of the other threads on towing for the wiring diagrams. There is a lot of electronics in that box.
The Throat opening is 1.25" and the Pin Diameter is .88 on 3/4" Screw Pin Anchor Shackle
- 4-3/4 Ton WLL.
I measured the shackle bracket width at 30mm(1.1811") which would leave .034" on each side.
If you look back a couple of posts at the front on picture that looks about right.
This is what you will need to add a four pin trailer connecter to a Bronco without the tow package.
The issue is the tail and brake lights are controlled with FET (Field Effect Transistors) and cannot handle any extra current draw.
My son-in-law added some ground effect lights lights to his 2019 Mustang. Connected them to the front parking lights so he would not forget to turn them off. Flat shut the engine down and would not start. So I removed them and connected direct to the battery with a fuse link alls well.
So...
