Did anybody figure this out for the 2019s? On my old truck there was already a footwell light but it was just a tiny bulb and only on the driver side. I added LEDs to both side and just used the existing wire. That worked great. Would love to add footwell LEDs to my Trail Boss that work with the dome lights.

I installed some RGB footwell lights this weekend (picture forthcoming) and part of the project involved locating a switched power source and preferably one with retained accessory power.  In the righ

Yes There is only one slot that is switched. It's the spade to the left of the 50 amp circuit breaker. Top right of this picture. You have to use a spade connection to grab it and split it off

Hooked mine up last night. Wired them into the dome lights. Thanks Smoothbassman!

I'm working on it today. I'll find the right wires and report back. I got the 1st part done with wiring this into the accessory power.

Yep.

 

I figured it out. 

 

As for the dome light I found the right wire in the harness that gives me the positive output that I need as well.   Pin 10 on the forward most BCM Connector.  2nd Gray wire.

 

I have that marked and ready for the rest of the install. 

 

In order to use this Kit how I want, I had to order a couple of set's of relays. Cost 10 bucks for these relays and all of the parts will be here on Weds.  I will assemble, bench test it Thursday and get it installed on Saturday morning.  I will have photos of everything after I get the wiring completed. 

 

It sounds complicated but it really isn't.  Just need an hour of time to wire everything up offline before getting back in the dash to install everything. 

 

More to come this weekend!

Can anyone tell me if they found an accessory powered fuse in the passenger side fuse panel. I have tested everything there and everything is hot. Even the open spots.

Edit: Found it thanks

You have to use a spade connection to grab it and split it off from there.

Add an inline fuse and your good to go.e7eb2a7e74c3b41fd2cf50aea95b32e6.jpg

what triggers this on/off? or is this just a constant 12v w/ ignition on?

It's accessory power. 

 

When the ignition is in Accessory mode or running that pin is powered.

Did you by chance stumble on the dome light fuse? I ideally wanted power only when the dome lights are on.

It's also in the passenger side A Pillar from what I have been told, but I haven't had time to tear into it quite yet. That's Saturday mornings plan before I head to the muffler shop to get some more bottom end on this truck.

Sorry.... I just realized you posted that before. Been a long week!

 

I not sure where to look for the BCM connector, can you help me out?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
