Wires in engine bay

[JnJJunk]

Hey guys working on my 1970 c10 and I have come across some stuff that I just cant quite pinpoint. I've looked on the wiring drawing and it is not really helping me out. Heres a couple pictures.

The first two are all on system. There is a red wire that runs into the fire wall, a blue and a black wire with a plug that was on top of the manifold, a green wire to the trans, and a green wire to the temp sensor on the passenger side of the block. Then there is a relay on the fire wall that all this comes out of. I thought this was the TCS system but I did not think that started until 71.

The last picture is of wires by the coil. The yellow one goes to the coil but the other two were just taped up in the harness.
