American autowire 67 stepside

[Shank]

I have a 67 stepside. Just installed the American autowire complete kit. The only thing I’m questioning about is my backup lights. American had 2 wires that run to the neutral safety switch. A green and a pink. Now the pink is saying that it’s a 12v ignition. Which it seems that it should be hot when the key is on. Well we were checking the rear wires to make sure they all were working properly. The backup lights didn’t. Well I put my test light on the pink wire and there’s no fire going to it. Am I missing something here? Shouldn’t it be hot if the keys on?
