Hi

I bought on 11/30 -12/1/24 a 2024 SR Pro with no max trailer tow package or trailer technology package.

The sales man sold me a spray in bed liner and a trailer brake. This Wednesday I brought it in for the bed liner and the trailer brake. The bed liner was done yesterday.

After 3 hours of working on the Trailer Brake Wednesday and a few more hours working on it today and frying a tail light control module (which they have to order and replace), today the Service Manager called me saying they couldn't do it.

I received some information from EV Mariner as to which dealer in Maine got his brake going. I offered the information to the Service Manager whom said he didn't care.

My son who runs the maintenance department for a contracting firm, works with another dealer for their commerical trucks says don't let Ford off the hook.

I have on the farm here semi tractors and other heavy vehicles.

It does not make any sense for afford to put a Class IV hitch (10,000# capable) and an anti-sway on a F150 lightning capable of towing 5,500#, but limited to 3,500# without installing a trailer brake, which is not possible.

I am openly for advice here.

The trailer brake and bedliner was wrapped into the financing.


Thanks looking for an idea here.

I installed my trailer brake controller in my 24 flash just today.

Ford part number is RL3Z-19H332-AA
(Part number for 23 and earlier is RL3Z-19H332-AB)

It took all of 10 minutes to install and another 5 minutes with forscan to update the IPC.

I bought it on "the bay" from FairwayFordParts, if you search that part number on "the bay" it will be the first result.

This is wrong for the 24 lightning correct for 24 ice trucks

What's the consequences of having it in my truck?
I dont know. I have to be careful of what information is distributed. I dont want someone to buy a wrong part and not know.
I know 100% the TRM part number for the 22-25 Lightning.

I do not know the consequences of the wrong one. MAy be none.. but not knowing I would not want someone to find out the hard way.

SO I have to make sure when a post is made with incorrect info that i correct it.

FOrd ships them with a specific one. I have a 24 Flash also and installed the TRM and dug into it all.

So you may not experience any issue but ford didnt ship it with that one for a reason. The 24 F150 runs Super Duty firmware. It runs a new EPROM as well .

Yeah, I can't imagine the tow package not including a brake controller, but if for some odd reason it doesn't, I've been using the Curt Echo bluetooth brake controller with my BMW X3 for almost a year and I'm pretty happy with it. The device almost looks like a small scope you stick between the 7-pin connecter and the trailer. The companion app is pretty rough around the edges but it works well enough and I didn't have to mount anything inside the car. On top of that, it's really easy to swap between tow vehicles.
+1 on all points.

This is honestly one of the biggest points of confusion for me and one reason why I ordered the wrong thing. All of them for the F150 say that including ML3Z19H332AB.

Appreciate your info/help. I'll scrounge up a ML3Z19H332AB module and get it in the truck.

Since you already have the pincher you only need the module not the whole kit

ML3Z19H332J

That is the module part number.
