No Start, power but no click

[thun]

I have full power. Everything looks good but nothing happens when I go to turn it over. The battery is brand new. I want to test the starter by jumping the solenoid but I'm having big trouble accessing the small post or purple wire. From the top all I see is the main post and 3 small wires to the right and I can not see the purple wire post. I can see the other small post that is farthest from the engine but not the closest one. It's a 454. Does anyone have any tricks or tips to access the purple post or how to test solenoid?
