Default Engine wiring diagram for a 70?

Im getting ready to layout the wiring in the engine bay of my 70 Malibu and it came with a/c but I removed all the a/c componets because i will not be needing it. What i would like to know is , is there a wiring diagram on the web i could look at or print off that shows the color and destination of each wire. I will be removing the a/c wires to reduce clutter and clean it up. But im not sure which ones are for the a/c. My car has no power brakes or power steering so i will be running just the alt. and water pump off the crank. Im putting in a electric fan to increase hp. I will be using the car as street/strip for cruising and some fun weekends at the drag strip.

You might want to sell the ac components.Could get your money back for the car.The wires are usulaly the same all years but can differ.Temp wire green.Oil pressure blue.Starter solinoid purple.Distributor pink or red.If usure check voltage.Sending unit wires are 5 volts.Just touch one to ground and see what guage moves or light comes on.Also if you can remove the compleet ac harness without cutting it you can sell that also.

Ive been working on the car today and got the a/c harness removed without cutting it. Ive gotten down to the engine harness now and have a question? There is a black wire with a purple strip on it and im not sure what its for ? The wiring diagram for the ss does not have it on there . I also have a relay with a green and blue wire connected to it , are these for the oil pressure and temp? I wont be using heat or a/c in my car because its for cruising and racing. Its a Malibu so there is no gauges just warning lights.

Sorry I missed this post. Not sure on the black/purple. Is it part of the engine harness or the forward light harness? Any connector on the wire, what kind? The dark blue and dark green with the relay sounds like TCS. You don't need that, I'm sure the rest of the TCS circuit is non-functional anyway.

EDIT: Could the black with purple be black with pink? If so it's power to TCS.
