Having trailer brakes is surprisingly a state by state controlled item. In the table linked, the state that surprises me is CT, just 1,000lbs. https://neighborstrailer.com/blog/do...a-trailer-2026

If you have no trailer plug on the bumper, you have two choices. Without electrics you aren't going anywhere. But you may have the actual wiring hidden behind the bumper. You have to look and see. At that point you need to complete the lighting part of the circuitry. But not the trailer brakes For that you need a controller. One approach is to go with a Bluetooth system. Another is to add in a trailer brake controller inside the cab. I don't like the knee busting boxes that you often see. My bias is the Factory unit, which based on people who have bought fake Ford Trailer Brake controllers on ebay etc, I suggest you get done by a dealer.

BTW, 4,000lbs is pretty light in my book. If your job is a one off, and can be done using a U haul trailer, then go that route. Their trailers are surge braking. That means they sense you are braking and the force of the braking activates the trailer's brakes using its own brake fluid.

 

Yeah.. My trailer NEEDS brake control so I think I found a local company that can install the entire thing for me so I have my light, turn signals, break lights and breaks for my travel trailer.. I still pretty new to the truck game so I think having a local company do it for me may be a good start.. I'm a muscle car guy and although there are so many similarities, I may just start myself slow here... getting older and more reliant on others..

 

On another note. I want to replace my current Transmission (which I think is a 435) with a ZF5 (small block), which I have found a local one in great shape, so I have the overdrive.. thoughts? Thanks again...

 

On some older model Fords there is a connector on one of the rear taillight harnesses that you would attach a harness to for the brake/running/turn signals. This harness would then have the trailer connector on the opposite end. If it did not have the tow package then you would need to run the wiring for an after market brake controller from the battery to the passenger compartment then to a 7-pin connector at the back of the truck. You would also need to add wiring for an Aux 12V line and all of the fuses. Relays are also recommended to ensure the battery isn't drained when the engine is not running.

 

Is your truck really a 1980? My 2001 E350 was ordered with a "trailer wiring prep kit" . You might have to physically pull wires to your dashboard to get your electric brakes wired in.

 

I think that is a great idea, let the shop get you set-up and safe.

I think you should start a new thread for this topic. I would put it under correct truck / year, and not under 'towing' for best results and feedback. Good luck
