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.

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.

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.

Is that what is called the K9 BCM? Is there only one BCM on our trucks(mine is a 2018 1500 single cab WT) The reason I ask is because after wiring in running board light suddenly my cargo lights and cab mounted brake lights no longer work. This of course makes me believe something I did caused this and now I need to troubleshoot this problem. :/ Oh lordy lordy , well I was at least right, I did do something to cause this. First, the brake light lamp which I replaced with an LED, was in backwards. There is the first problem solved. Next I went to the passenger side cabin fuse box and found that fuse number 10 which feeds the cargo lamps was......drum roll...........missing. What??? Ok I must be wrong so I recheck the diagram but everything is in proper place except this 15A fuse in position #10. I think this qualifies as a genuine "senior moment". I do not remember pulling that fuse and I'm pretty sure the cargo lights worked before I started the running board light project and replacing the incandescent bulbs of cargo/upper brake light lamps with LEDs. Ok, I guess I'll have to accept that as a senior moment and move on but wait......there is one more thing bothering me, 15 amps for cargo lights???? Well I put in a 5A fuse. 15 amps is getting up there and the size of these wires make me uncomfortable. Per diagrams I've found the cargo lamps are all that on this circuit and I'll sleep better know the 5A fuse is ready to open circuit at the slightest problem. Well I just had to report what I found even though it makes me look a little dumb especially for someone who was one an electronics tech. I just wanted to report the truth so nothing in my previous post causes someone else to take a wrong turn.

But...wait, you could have used a bidirectional diode setup. Then you could explain the standing wave cancellation using symmetric forced electron induction along the magnetic biosphere grid lines producing equalized photon emission on both upper and lower planes. Ok, all the BS behind and yes 95% of that was BS that's a great tip I have to admit I get nervous shunting wire plugs diode or not when I don't have a schematic to follow.

Sorry for my ignorance, assuming I get this info on my 2018 Silverado 5.3 WT with only convenience and tow packages, what can I use this for? Is this just info a shop might need to work on my truck or is there something else I can use this for? Thanks

Just feedback on what I did. Yes, I purchased the Borla ProXS Muffler on Amazon Borla 40359 . Cold start might just be the loudest. It did make a difference and sounds pretty good at full throttle. As far as drone noise there is none. Actually at highway speed I don't hear it at all unless I really get on it. I would like it to be a little louder but worried taking the resonator out might make it have drone noise on the highway. Hope that helps others interested in the muffler. I did no other changes but swap out OEM muffler for this one. The muffler is a straight through design with baffling but nothing directly blocking airflow. As far as I can tell there is no real performance improvement just a somewhat better sound.

As a previous electronics technician I despise the thought of adding resistors to patch(not fix) the problem when changing turn signals to LEDs. 1 because LEDs are almost 10 times more efficient than incandescent then we turn around and negate the gain by adding "load" resistors (to increase current) across the same circuit to attempt to trick the load detection. 2. Because adding these resistors which run very hot introduces potential failures or even a fire under the right circumstances. 3. Folks who are not used to proper wiring techniques may actually make their turn signal indicator system less reliable. Loss of turn signals could result in an accident. It seems from previous feedback the real fix is to change programming and that is overly expensive. Reasons 1 and 2 are enough for me that I'll leave the turn signals OEM but I did upgrade the reverse to brighter LED and may do the brake lights if they don't cause an error.

Awesome, this is now on my to do list.

I'm looking at maybe the Borla Pro XS to replace my stock muffler. My truck is a 2018 Silverado 5.3 w/just over 1K miles. I just want a little more sound, hopefully deeper too. I do not want a loud obnoxious exhaust. Anyone know what Borla model # is for my truck? If not, anyone know what size in/out I need, then I could research and find what model I need. I looked under truck and it appears to be offset intake and center output and states reversible. If it's 3" then maybe this is the one I want. Borla Pro XS 40359 . Thought I'd ask here before I order though since someone may know what I really need. Thx in advance, Don
