Where to find a BCM schematic?

[Gryphon762mm]

There was a GREAT schematic and pinout of all the BCM functions in this thread: www.gm-trucks.com/forums/topic/169208-brighter-led-drls-yup

 

Now the pics are gone. Anyone know where I can find them for the 2014/2015 Sierra (I presume the Silverado is the same)? I have some pretty funky wiring projects in mind that I want to try, like making my Whelen lightbar do sequential turn signals with my stock ones.

Have you tried contacting the poster of the schematics and find out where they got them?

Have you tried the Upfitter documents?

Yes. The electrical manual is chock full of useless electrical diagrams and try as I could, I did not see the BCM connector pinout. In all 898 pages of it.

You didnt look hard enough

 

I use it all the time, use this link: https://www.gmupfitter.com/files/media/photo/474/2014%20BBM%20Electrical%20section_10_18_2013_WIP.pdf

 

First BCM connector pinout starts on page 143, remember, the diagram shows the connector disconnected facing you, dont fry anything!

I don't know how I missed that, I probably had the wrong manual. Thanks a million!

I wouldn't have been so polite. Considering his snotty first response ...seemed like either he couldn't read or it wasn't the info he wanted help with

It took me a while to find it on the page when I first used it too, they do not have the best organization that is understandable to average people.

 

I thought his first post was ok, sure, not the best, not offensive either. I rather help a brother out ;)

the electrical manuals just got tougher.. in the 2018 body builder upfitter doc, it doesn't even list the BCM. so, how do I find it in the schematics?
