Default '69 GP wiring harness differences

I just changed the dash in my '69 from green to black. The black has a 6319 hash harness. I don't know what the original one was. Original car has 428/no gauges & AC but has cruise and cornering lights and I see the engine bay harness has a couple wire different in the plug that goes to the fusebox.

Where can I get a good wiring schematic? I have a basic schematic for a '70 GP from the library. What about build sheet codes? I have a pretty bad one but if I can find it, I'll post the code.

How many different harnesse's were made in '69? Iknow the steering wheel isn't a perfect match, but I like it for now. The '69 interior I got 3 years ago is immaculate! I wish there was a console but I got everything else. With 79K, there is no rust on any screw and it looks great!!!

I'm not sure how many dash harness variations were made, but the 1969 Service Manual has a complete color coded schematic with all of the different options available.

Did the '69 have a TCS control? Let me say that I didn't tear up any frnt/middle/rear wiring harness, I just changed dashes that looked like the same wiring harness. Also there is no electric window or lock harness on this schematic. Thanks for all your help!

My '69 does have a thermo vacuum switch, here are some pictures of the 69 service manual (sorry, I don't have a scanner) for the wiring of the front end, cornering lamps, and the other power options available.

IIRC, both the p/w and the p/s have a separate live feed/harness directly from the fuse block, the window feed goes to a relay roughly by the emergency brake release and the seat goes directly to the seat (follows the intermediate harness).
