2023 F150 Wiring Question / Update Issue

[WBravo]

Evening everyone.

I have a couple of questions here. I'm working on my 2023 F150 Tremor 402A - I'm installing a high in hazard light package for work, since I seem to use my personal more than anything else, and I've hit a bit of a snag.

The 'control board' that handles all the lights has multiple inputs to integrate the unit with the rest of the truck, in particular, three inputs that I need to fill: 1) 12V Ignition, 2) 'DAY' Input, and 3) 'NIGHT' input. What I need to find out how to locate is three wire, which are hopefully accessible at the lower passenger kick panel, that I can supply these with.

The ignition is self explanatory, 12V+ only when the ignition is on.

Day and Night are what controls the illumination level of the buttons on the controller that I have installed. So I'm looking for a way to send 12V+ to each one for those when the truck is in 'day mode' and 'night mode.' This might be simple and I'm just not thinking of it the right way, but I'm not sure where or what wire/fuse to tap in order to do this. If anyone could give me a direction I'd greatly appreciate it.

Incidentally, if anyone knows of a place tap into the 'brake light' signal inside the cab by those, that would be amazing. Otherwise, I'll be bringing it in from the outside as I have with the others.

If you need the information on the light controller it can be found here:
Feniex 4200 Datalink Controller

-- Aside from the above, I also have an update (I believe it's the window control OTA) that keeps hanging and having to be rescheduled, could I get someone to pull the VIN and see if you can ID what's causing the hangup?

VIN: 1FTEW1E88PFB44041


Any assistance is greatly appreciated. Cheers.

Search on the forum "TOPPER BRAKE LIGHT" . There is a wire under the hood that you can use for the brake lite cct. The thread explains it all.

Day/Night...I would just put a toggle switch beside the controller and just select the required lighting level.

Is there a relay box that goes under the hood for the high current loads?

Thank you, I'll check out the thread in just a bit.

Regarding the switch, I want to avoid adding switches for it if I can help it. I'm sure there is something getting power when the truck detects low light, such as ambient lighting or the like, I'm just not sure what or where it's at.

The 'controller' is broken into two parts, the switchboard which is mounted in view, and the control board which is hidden. The board itself is where the relay and switching happens (10A per channel), however, the lights themselves (front bar, rear bar, rocker bars, etc) from a added fuseblock under the truck (12+ constant) fed directly from the battery with a high amp breaker at the battery box, the rest of the wiring, for the individual functions are just signal.

IE:
Front Bar
12V Pwr - Constant from the fuseblock
Attack Pattern - 12V+ from control board on channel 3

Way less headache than having to put on standalone relays.

It has a direct feed from the battery for the ccts? Don't connect the neg directly to the battery. Go to a bolt on the frame. The BMS needs to see the draw on the battery. Ambient lighting should work if 12v is only on when headlights are on. If they are dimming, then that will not work. I don't have ambient lighting in my truck, that is why I am asking. I can't think of any other way to get day/night switching.

Yessir, it has direct feed from the battery and individual channels for output. And yes, as you suggested, the ground for the unit is to the truck and not directly to the battery so that BMS continues to function normally.

I'll see if I can hunt down the ambient or something like it, I'm sure there is probably something in the truck manual or a service manual, but dang if that thing isn't a TOME, even with search functions it's a handful.

I appreciate your help all the same! I'm going to play with it some tonight since I got lucky and already had a tap to the brake (STOP) lights, hooked it up to my rear light bar and sure enough, my brake pop functionality on it worked like a charm.

NP.... I can not think of a day/Night toggle ..... unless you pick up a dash light under the Sync screen, it is the only thing I can think of.

For the Day\Night, since each requires +12v, I would think the easiest way to do that would be a SPDT relay, hooked up to either the parking light, or headlights. 12V into the relay, NC would be the Day signal, NO would be the Night.

Look for the f150 police responder upfitter guide. That should help you locate some of the pinout's and harnesses you need. Some might be specific, but they generally show how to find what you need.

We have the brake and dimming on our trucks with the 4200.

But, hate to tell you this but the Feniex stuff has been nothing but problems for us. The Quantium light will randomly change colors. They default to blue. They supposedly fixed or have a fix in the works. Their headquarters is done the road from us and swapped out some lights with prototypes.

And sometimes when we start the truck the ignition signal to the 4200 misses when it's booting up the remote display and won't cycle on. We also have issues with the Feniex stuff drawing down the batteries. Make sure you have a relay disconnecting the brain of the 4200 completely. Just the remote display isn't enough. We have onboard battery chargers tho, due to the computer always on when parked etc at the station.

We went back to Whelen due to the issues.

It sounds like you’re headed down the path of what rightranger mentioned. Another (more complex) solution could be something like this controlling the 12v input to your controller, assuming amperage is ok. If not, a relay could be used. Btw, I definitely don’t endorse this brand, it’s just the first thing that returned when searching.
