Lighted rear ford emblem wiring question...

[Shadyant]

Hello all,

I don't see this posted but please forgive me it is is posted elsewhere.

I'll post my actual question first so you don't have to read the entire post unless you really want to

Q:
I purchased a Reese officially licensed lighted rear ford emblem (Amazon) The sizing is perfect and the hardware install went fine...The wiring is another story.

The manufacturer "says' the brake conversion module is internal (which I highly doubt).
This module is intended for vehicles where the turn and stop lights are on the same circuit...
So does anyone know IF in fact the 2019 Ranger turn and stop lights are on the same circuit?????





Additional details if you desire more back story...

I'm 99.9% certain I have correctly confirmed my STOP and TAIL Lamp signal wires using a circuit tester and turning the tail lights on and off and having the brake pedal pressed on and rebased as I held the tester...so I'm pretty confident the correct wires were identified.

When I have the two wires from the emblem connected (one to the tail/parking light wire and one to the stop/brake wire) the emblem is lit on the low range as expected, however, my two factory brake lights act like they're engaged when the brake is NOT depressed...when I depress the brake the factory brake lights do nothing of course because they're already engaged some how...my center mount brake light pulses correctly with the pedal press and the emblem does NOT get brighter as it's supposed to.

If I remove the wire to the STOP signal wire then my factory brake lights and center mount lights act as expected but of course the emblem doesn't get brighter...

Basically I'm only able to use the parking/tail light function and have the other wire disconnected.

Thanks in advance!

The stop/turn signals are not on the same wire (circuit) if you have one wire for stop and one for turn.
EDIT
The 2 wires on the emblem are for (1) park/tail light and (2) stop/turn, of which the Ranger doesn't have #2 (I believe)

maybe this diagram will help...

I was looking for that!! I knew I had seen it but couldn't remember where it was.

Don't know if this will help, but have you checked for a good ground connection? You would be surprised at the weird things lights do when there isn't a good ground. I changed out the lights on my boat trailer with LED's and I had an issue similar to this and making a better ground to the frame fixed the issue.

I appreciate the quick replies all!!

I’m going to double check the ground and the if that’s not it, take some time with those pin diagrams and hammer this out.

A Sat project haha.

I’ll report back on the fix (hopefully) once I find it.

Well...
So far...failure

Based on the pin diagram, ive confirmed I have it wired correctly and double checked the ground (even moved to a different ground)

No luck. As long as the emblem stop wire is connected to the vehicle stop wire, the Ranger’s rear brake lights stay engaged with no pedal press (emblem doesn’t get brighter either).

I’m stumped.
Perhaps the dang emblem is faulty.
My money is on the CAN BUS system though. Even though it’s not technically a two wire system, it’s acting like one and without a brake conversion module I think the CAN BUS Is the culprit.

My only other thought is that the emblem stop wire must go directly to the single wire connected to the taillight brake LED bulbs themselves, essentially before the BCM which is always hot.
Of course now I need two figure out how to pop out the taillights assembly. I’ll look at some threads to see if that process is already posted.

Was checking out another thread and saw your emblem. Did you ever resolve this issue? If so care to share, poss w/pix?

Thanks!
