Anyone have a link to the pinout of the PCM

[blackbox19]

I have a 2001 yukon and need to know the pin out pf the engine computer.
Trying to figure out where the security signal comes in to tell the computer to do what it does.
I have a way to create a signal but need to know what wire it comes in on.

OR how does the security work or tell the computer to work,

Thanks...

is there a page in the manual that shows what the abbreviations are in each line of the circuit?
Example the CPP switch signal?
Or what those LOW REFERENCE circuits are for?

or a link to a free fsm would be sweet too... I found a few for silverados but those are cable drive... Mine is wire drive and I want to be 100% sure when I go to cutting and making changes...

Why not just pay the cheap price for alldata?

 

[blackbox19]

if I pay anything it will not be to them.
I can get a FSM for 14 bucks.... But if someone has it for free why pay that... Kinda like that rockie mountain company selling Vats bypass for 300 bucks... SOME sucker has paid that..... when ebay has the same bypass for 14 bucks..
I literally have a huge terabyte hard drive full of FSMs I got for free. It may take me a few weeks but I find this one too..

OK..... I sleep well at night. over this..
As I dont sell the info nor do I share it...
I glean from it the information I need and share that with others as a way to help them. I wanted to be able to help others also with this pain in behind issue of security system faulting off and leaving them stranded. I know I can cut a wire and read the resistance of what the key cylinder should be sending over to the BCM and splice in the resister to get around the key issue... But if that BCM faults off like mine is doing I want to wire in a signal generator to make the truck run... If someone wanted to steal a truck they already gonna do it so the security thing aint stopping anyone.. Heck I can take a cleared pcm and a could wires and have any truck I wanted up and going..
