Cargo Lights on with Reverse Lights

[whaler]

Did this on my last two trucks. Worked perfectly. Not sure why you guys are having issues? You can’t be doing it right. Go through this thread carefully. It’s all there.

I was going to suggest a close-up photo of the BCM, maybe jumping the wrong pin(s).

I just did it again today. I happen to hop into the passenger seat today and turned on the ignition to refresh my SiriusXM radio. I then turned the car off and closed and lock the passenger door and the radio continued to play. Wasn't till I opened the drivers door and that it turned off. 

.. that's because the RAP senses the drivers door open/close.. your passenger can exit the vehicle without disabling the RAP

2018 Silverado WT, Sgl Cab, Std. bed,  I did this mod(straight wire) which my wire was too small.  If you run into that just double over you wire ends and solder.  The result?  Well Dang! this is nice!  Another advantage which I haven't hear mentioned is that if someone is tailgating you just press you cargo light from inside the cabin and wallah, your sending you upper cargo lights, your reverse lights, I had added LED tailgate light which also light up white when in reverse mode, and you upper/lower brake lights.  That should get a clear message to them tailgaters!  I had already upgrade the reverse upper and lower with super bright LEDs so I love the fact I can just reach over and hit the in cab cargo light and send the message.

All this said I just hope this never creates an issue with the any of the BCMs but for right now I'm loving this and probably the easiest mod I've done.  Thanks to those who published which connections to shunt.

What are you using to enable the cargo lights being able to be turned on while moving?

[2WRDR]

Dang it, I spoke too soon.  I just went for  a drive to the grocery store and well, no can do.  I didn't even think about the fact that being in drive the cargo lights are disabled.  

 

Oh well, I still like the mod overall.

Shhh, but If you slip the truck into neutral the lights will work.

Did this mod today and it works great, just wanted to drop a note to say that on a 2018 silverado that the wire color are different gr but the locations are the same if anyone else runs across the same issue. Thanks again.

Must be a before picture.  No wire, nor diode.

You have another picture with the diode? It goes from brown block blue wire in upper left corner to pink block brown and white secon from the upper left? For the cargo with reverse right?

Yes, it does. My photo is from my '15, after I did the cargo w/ reverse diode mod.
