Diode Dynamics C1R + Brake Hitch Reverse Light Installed on my '25 Lariat w/ 4k

1. Remove the 7pin connector from the back side of the bumper
   1. You have to remove a little grey plastic retaining pin from top of the connector which can be challenging to see on your back under the truck
2. Connect the Diode Dynamic 7pin inline harness to the OEM plug with the other end connecting to the rear of the bumper
   1. If you stop here you will still not have brighter red brake light on the puck
   2. 
3. Remove both tail lights
4. Use the included double inline additional power line to connect to both OEM tail light wire harness and back to the taillight
   1. IMPORANT - make sure to run the cable high along the underside of the bed to avoid the exhaust on the drivers side. I have the Mabett underbody cavity cover which helps
   2. The single plug of this Diode Dynamic provided harness will be routed to the hitch area
   3. You have to connect to both tail lights - if you connect only to 1 tail light you will have a constant flashing bright red light when you apply the brake with a turn signal indicated on that side
   4. 
5. Disconnect the Red wire's plug on the Diode Dynamic's 7pin harness and connect the double tail light harness you just ran
6. Use the cover from the now double inline Diode Dynamic harness you just routed from the tail lights to cap the disconnected plug
7. Test for functionality
8. If you do not like the flashing high red light on brake you can cut the purple wire on the Diode Dynamic harness but I would not recommend it because it could break the hazard flashing on the hitch puck
9. Zip tie the wire harnesses up making sure to leave some slack on the cable that plugs into the puck to allow you to take it out when you are towing.
   1. Again make sure you have the wire aware from the exhaust.
10. I removed the plastic retaining buttons from the puck to allow installation of a locking hitch pin.

• Unlocking the truck turns on my LED tail light accent lights as well as low red of the puck
• Applying the brake flashes the brighter red light a few times before becoming solid until releasing the brake
• Brake flashing/solid is priority on puck when turn signal is applied
• No change to puck light for either turn signal
  • meaning if turn signal is applied but no brake and headlights are off then puck is off
  • brake with turn signal will show the few flashes on the puck before going solid
• Turning on the hazards will do a constant flashing of the brighter red light
• switching to reverse will always overwrite the puck to output the white light

Just finished up installed a @Diode Dynamics C1R + Brake hitch led module in my 2025 Lariat Hybrid with 4k tow and wanted to document some of the things I ran into to help reduce anyone else's headaches. Since I have 4k tow with Lariat trim I have both Co-Pilot360 and Co-Pilot Assist 2.0. This did not impact any of those features like parking sensors, bliss, blindspot, adaptive cruise control, etc for me and did not get any trailer connection alerts on the hud.

Looking at Diode Dynamics only the the C1 shows as supported for the 2022-2024 Maverick. I ended up purchasing the kit and it worked plug and play but their page was not super apparent to me that it only supported low red running and reverse on the puck - the brighter/high red does have a pin on the puck but it is missing the LED chips on the board so no option for a manual wiring solution. The wiring harness was a single inline connector to only one of the rear taillights and worked fine on my 2025. I really wanted brake with modulation/flashing so ended up returning it. The folks as Diode Dynamics were wonderful to work with and no issues at all with the return.

Doing some digging found a few posts (including a Google search listing showing a DIY page that appears on have been delete on this forum) about using a kit from a F150 instead.
A requirement of this is you have to have 4k tow - ie the 7pin trailer connector.
Ended up purchasing a DD7649 - https://www.diodedynamics.com/hitchmount-led-pod-reverse-kit-for-2021-2023-ford-f-150.html

Installation process that worked for me but YMMV:

1. Remove the 7pin connector from the back side of the bumper
   1. You have to remove a little grey plastic retaining pin from top of the connector which can be challenging to see on your back under the truck

9. Zip tie the wire harnesses up making sure to leave some slack on the cable that plugs into the puck to allow you to take it out when you are towing.

Day and Night testing:


FInal thoughts:
I really like this product and was a pretty easy installation once I had the right parts. Spent maybe any hour getting everything buttoned up and was plug and play without any wire splicing needed. I really wish Diode Dynamic would clean up the Maverick product page to A) make it perfectly clear that the version currently listed does not support brake, B) offer a 7pin with the tail light harness on their Maverick page by specifying it will only work for those with 4k tow/7pin already installed, and C) in their Maverick offered 7pin box remove some of the extra F150 harnesses unused to reduce the sale price a few bucks.
Cannot say enough good things about Diode Dynamic's customer support and ease of returning with a prepaid label. It really built my confidence in their warranty should I need it down the road.

What did you do to allow the hitch pin to be used? Did you drill it out, or is it set up for it?

Hi,

Thanks for posting this. I have a 2025 Maverick Hybrid, and the kit shown in the photo i posted is the one I’m currently using. It was the only kit I could find. While it does work, I’m getting intermittent trailer disconnect errors.

I’m fine with purchasing the correct harness. Do you know which harness I should be using? I looked at the F-150 kit on the DD website, and it appears to include several different harnesses. I’m not sure which one(s) I need or how many to buy.

Thanks in advance for any guidance.
