Guys,
I would like to make the whole truck unlock with a single press of the unlock button on the keyfob. In the past on other vehicles, I had taken a diode and put it between the driver door unlock relay and the other unlock relay, but the CK trucks now do not have that wiring setup.

Would there be a simple connection method that someone could help me develop?? I am thinking it could be all done from the in-vehicle BEC (fuse block) on the driver side, but unsure due to our use of the door modules now.

Thanks in advance!!!

The way the truck is set up, if its not available by programming I don't think there is going to be able to do it.

Well that just plain stinks! Is the reasoning here that data is being sent to the drivers door module and not a real unlock signal (i.e. the driver door module sends the unlock command through copper (inside the door) to the lock motor)?? What do the connections in the IP BEC do? If I remember there was a fuse and plug for the driver related stuff, and there is also a unlock relay in there as well. What signals are there in that BEC that may relate to unlock? I guess I need a schematic.

I know on some vehicles there is the opportunity to "customize" the vehicle settings by pulling a fuse, pushing buttons three times, and standing on your head. On the CKs, the only customization comes through the DIC.

Sometimes I wish we could go back to the old days.....
This bit of customization continues to be one of my pet peeves.
