wires for trailer brake controller '24 Ranger?

[HWMTB]

Good news. progress is being made.
The constant 12v on black is encouraging.
Looking at the diagram of the 7-pin I posted:
From my understanding, when you push the brake, you should get THREE lights on the tester:
Right brake light (brown wire)
Left brake light (red wire)
TBC output (blue wire)

Ohh!!! Good catch sir! I just double checked and everything checks out.

BRAKE PRESSED = 3 LIGHTS on the Curt tester:

• 12-Volt (Constant)
• Left Tail Light (Constant when braking, flash with turn signal)
• Right Tail Light (Constant when braking, flash with turn signal)

TBC OUTPUT on the Curt Tester:

• TBC lights up on the Curt tester when the manual override is pressed. That's great!
• TBC is NOT LIT with only brake pedal is depressed. ***

*** I also would expect the TBC Output LED to light up on the Curt test WHEN THE BRAKE IS PRESSED but it seems that the Redarc needs to some "resistance" (like that of light bulb) to activate. The Curt tester may not provide the expected resistance so the TBC output stays off. I'd have to rig up some light bulb test like @chino101 did to know for sure. I gotta go again and re-read RangerDangerStrangers post where he used an oscilloscope.

Did you take a look under the bumper? Did the installer actually add a harness with connectors, or did he splice into wires?

So, it appears everything was spliced in! I guess that is fine but I see now (based on the picture) they did a poor job protecting the connections from weather! I wish I looked earlier before the salt this winter.

Yeah, splicing is not optimal, but it tells me all the wire for the 7 pin are there.
When I do it, I'm going to find a good set of connectors. male and female, that I can use, unless and aftermarket manufacture comes up with something.
FYI, this will be a summer project for me.

Where did you hook up the red , that's the brake input to the TBC.
Refer to post #79 for connection
And post #80 says The engine MUST be running, not just KEY ON.

The red wire from the controller goes through the harness and connects to the port under the dashboard. If I'm reading the diagrams in post #79 correctly, the red wire should be connected to #12, the brake on/off (BOO) connection. Yes, the engine was running also. The fact that the Redarc isn't calibrating (with or without trailer) is concerning also. At this point, I just need a trailer and see how things work. LOL

Hi all, i have also a 2024 LTE (without the tow package).
If i use the plug und Play Wire TPH-007 to connect the Redarc Tow Pro Elite, ther is no Signal Conditioning Module included like in the REDARC TPWKIT-012 wiring kit.
Is this a problem?
please excuse mi englisch (Panama)

That's hard to say, as US Rangers are different in wiring than Rest of World Rangers. I do know 2019-2023 US Rangers did need a Signal Conditioning Module. Ford, Redarc, or Curt haven't come out with an official TBC for our new gen Rangers.
As you see, users here are experimenting with a solution for US Rangers, which may not work on ROW Rangers, therefore I'd recommend you use what is available in your region.

And why the plug and play harness don't have a scm? If it's necessary for Ford Models 2019 to 2023?

 

[Jason B]

The Ford authorized TBC for 2019-2023 U.S. Rangers DID come with an SCM, only they called it a Lumen Module. It's the one at the bottom of this picture. It was troublesome to install because the SCM/Lumen had to have a wire connected to the 3rd brake light at the top of our cab.
The kit is Ford PN VKB3Z2C006A

Just to confirm, you all have a Ranger with a BASIC Tow Package, correct?

Hey Y'all,

I been double checking my install to make sure I followed every step you have all suggested. I'm confident my install is correct.

If you're been following my posts, you might remember I had issues with my Redarc Liberty Tow-Pro not calibrating. I thought 12-volt power was dropping with the ignition off; that isn't the case. Using a multimeter, I was able to confirm 12-volt power is present at the TBC when the ignition is turned off. This means the Redarc should be retaining calibration settings. Sadly, it isn't.

I'm pretty confident I confirmed my second concern to be true: There is no brake pedal signal to Redarc TBC. With the engine running, I checked voltage over Pin 12 (the Grey/Org wire) with brakes released and applied. No voltage! .. meter read zero!

I called my Ford dealership and was told, "the port is there so it should work." So I did the next best thing... called another Ford dealership. That dealership said the "computer needs to be programmed" to activate port and of course it's "a very 'difficult' procedure" to program the computer so it's going to cost at least $100. Difficult? What a joke.

So, I now have a service appointment on Monday, Feb 3rd. I'll report back then. Hopefully this resolves the brake controller issue. So, @Jason B, be ready for POSSIBLE trip back to the dealership to get that port activated! (I'll let you know).

Sorry to hear about the challenges.

I have the $495 "Trailer Tow Package" which has the 7 and 4 pin socket installed at the factory.

I never tested the "pin 12" as shown by @RangerDangerStranger in https://www.ranger6g.com/forum/threads/wires-for-trailer-brake-controller-24-ranger.11415/page-3

All of my testing was done on the 7-pin connector/socket side.

Certainly a bummer on your findings...but yes, mine has the basic ($495) trailer tow package.

Have you tried disconnecting the negative battery cable for a few minutes then reconnecting ( turn key on when disconnected)? Don't know if it will change anything in this case but it might not hurt to "reset" some modules (plus it's easy and free).

Sounds plausable, w/o at least the basic Tow Package, the connector remains unflashed. That's new information. Good call on your part testing that pin, and lucky you found a dealership that even knows how to flash it. Good you had the engine running when checking for voltage at the BOO/BPP pin. Not running you get nothing. Seems like you verified the rest of the function. Sounds like it should work. I haven't gotten around to installing mine yet. I'm 100% on it working at this point. Red Arc calibration issue sounds like a Red Arc issue, though it may need the brake signal in to calibrate?

Thanks for the additional info. Bummer that it has to be activated by Ford, which seems like an odd duck. But what do I know. It could be because everything is controlled by the ECU or BCM.

Just like I figured. If the basic tow package is there, all you have to do is get the trailer brake turned on by ford. Same way it been for a long time. Still cheaper than buying the higher end package. Gotta look at it that way.

If there is a way to 'turn on' the factory trailer brake controller that would be great. In my investigation and simple teardown of the dash bezel, I couldn't find the plug for the trailer brake gain controller. Which is this item:

Probably just need the wire harness to go from the block to the controller. I will stop at ford parts sometime and get them to print out the 2024+ schematics and parts list.
