Default 1970 400 Factory Plug Wire Loom Locations

I just bought a set of 1970 plug wire looms for my GTO. I was wondering if anyone had any pics or diagrams of how these bolt to the heads.

This highlighted photo should get you started.

Each of the two tall ones carrying 4 wires goes on the intake manifold side of the at the rear..
The ones carrying just two wires go under the front lower valve cover bolt.

You should be able to figure out the other ones after those are on.

The AC looms are different. Does your car have AC? I had to use the 69 AC looms and the one for #1 & #3 is different than what 1970 used.

Got them installed and the look great! I have Vintage Air, so the compressor wasn't really in the way.
