OBS Chevy Project Truck LS Swap Wiring Issue MIL Check Engine Light Stays on with NO Trouble Code

The last wiring issue (I think) is the MIL or Check Engine Light. For some reason, it stays on all the time. Even when the MIL wire is NOT plugged into the LS or OBS pcm. I figured it out...finally! 
One thing that threw me off as well, was that the color of the MIL wire is not consistent throughout the truck. The wire on position A7 on the OBS truck pcm was a light brown or beige with black stripe. The other wire I found that looked like it was NOT an MIL wire, it was a dark brown with stripe. Having a factory electrical manual was what saved the day. I found the correct position for the wire to be #419 on the schematic. Once I found  the wire and removed it from the small harness and connected a wire to it and ran that to the LS pcm, all was good. Thanks for watching!
