Blazer steering column help
 

Hello All,

I just recently acquired a 1973 Jimmy, the rig came from a vineyard where the farm hands lost the keys to the ignition so they installed a push botton start with a toggle switch they cut the little metal rod that goes to the on column ignition switch and lots of wires. I went to the wrecking yard and got a column with a key and tilt on it and I want to install it. Unfortunately the farm hands didn't really leave me a wiring diagram to use to uninstall the toggle and push botton start. I was wondering if there were any wiring gurus that could help me. Below I have some pictures of the toggle and push botton.

Ive looked at general wiring diagrams for this rig but i cant decipher this. Plus gm says there is supposed to be a brown wire for accessories? I cant find it. Im thinking this is an aftermarket harness... Any help would be greatly appreciated.
