1974 Scamp some assembly required

Now that the engine and transmission are in and the shifter linkage is all hooked up, bodywork is close enough, we finally made it to the point where my skills get to shine. Wiring.
The car came with the original 74 wiring harness but I don't think I'm going to use all of it. Little butchered up and I want to do away with the extra seat belt interlock crap. It came with extras, a really nice 73 harness and and equally nice 72 non ECU version. It will be a mix of the 3 for the engine, dash and rear body. Probably going to use a little bit of everything.
I think I'm going to do it kinda like we do at work, lay them on a 4 by 8 pieces of plywood so I can check every wire and connector.
Of course while I'm doing this I will restore the dash, along with the instrument cluster, radio and heater bezel, and the glove box door. Dash pad has a cover and is good enough. Will continue through with the heater box also.

I've learned a lot and appreciate the help I've received here. More fun to come!
