Engine wiring and other

[Warren Steeves]

I have a 72Blazer and I am wondering about some of the wiring.Does the yellow or purple wire go to the S terminal on the solenoid?Does my white and yellow wire that is crimped together with a 2 prong male connector go to the resistor,or does the brown with a white stripe?Where does the blue wire with a rubber boot with single female prong go?Also there is a 3 prong male plug on the right side of the Turbo 350 just below the trans cooler in and out fittings,what is it for?I got this harness quite a few years ago from Golden State Truck Parts.This was a frame off restoration that as you know can get prolonged some times.I would greatly appreciate any and all input.Thanks
