I have a 700r4, it was built less then 9 months ago, and the company does not recall exactly if they installed a NC or NO switch, how can i test externally?

i have everything i need as far as data except one thing.

I located which ports are which, ABCD etc, and wrote down the Stripped Tan wire is Ground(terminal D), Purple wire is TCC Solenoid 12+, and Green wire, 4th gear pressure switch...

I dont know is the 4th gear pressure switch is +(pos) or -(neg).

I want to install a light, and if trhe light lights up all the time except 4th gear its a NO, and if only in 4th its a NC switch.

From there i can devise the best way to create my own TCC lockup system...

Chances are the switch will be grounded.

thats what i'm thinking but i need full assurance, because, a diagram i have, shows it as +12v...

but whether i am reading the diagram correctly is my question, i dont want to burn up anything, so i am trying to be 100% sure before i screw with it all...
