Does my ram have a fuse for the headlights?

[2010 Infantry Vet]

The factory plug has power in one pin, and no power to the other 2 pins.
I tested the retro plug, and none of the 3 wires have power.
There has to be a headlight fuse somewhere that is blown.
Parking lights work, but no headlights.

Had problems when I was fixing my hids. As far as I could find there was no fuse. When I popped off the negative terminal for a few seconds and reconnected my power supply came back. I'm guessing the bcm shuts it down when it senses a short or fault.

+1 on let the pcm/bcm reset. They computer will kill the circuit if it senses something wrong.

Thanks for the response. How do I reset the BCM?

Thanks for the response. I am just running stock halogen bulbs in the factory projectors.
So do I just disconnect the negative, and not the positive?

That should work. Leave it disconnected for 30 mins or so.

Is this a new problem or still trying to figure this out from about a month ago?

Have you added any other lighting that you would have tied into the factory wiring?

Disconnecting the battery should help.

There are a few fuses related to lighting. Probably different on a 1500 so you'd just have to check your fuse box.

For the factory truck connectors, can you point out each of the three pins on the black and green connectors that do and don’t get power? In your first pic with the green connector, you are probing the low beam circuit and it appears you are getting power. The middle pin on that connector is ground, so you won’t light up on that one. The last pin is the high beam circuit, so you’ll have to turn on the highs for that one.
There’s only one fuse that handles all the exterior lighting, but the TIPM will protect itself from a current overload at any given light circuit. If it senses an overload, it will shut that circuit off until the headlights are switched off, then it automatically resets itself.

It took me disconnecting the negative battery terminal. I just popped it off waited like 15 seconds and put it back on and it was reset switching off and on didnt do it for me

Do you think my stock connection is bad, and not transferring the power to the retro harness?
I might try hard wiring them if that's the case.

Thank you so much for explaining that.
So my tipm circuit is working properly, and my factory harness is getting power, but power is not being transferred to the retro harness some how.
I might try hardwiring them.

Yes, I said *** it, and just left it alone now that its being parked in my shop, and being used to take measurements for my 12" lift. No I haven't added any additional lights. Thanks for your reply.

Double check the connections in your harness. It could be something has simple as your ground in the retro harness being in the wrong location.

If resetting the bcm doesn't work, I'm gonna hard wire the damn thing.
Enough is enough.
