I was pulling the plug out of the back of my nitrous pressure gauge and a black wire pulled out of the plug and I have no idea which slot it goes in. It is 2 month old autmeter cobalt nitrous pressure gauge does anybody know where the wire goes? Here are some pics of both sides of theplugs any help would be greatly appreciated.

Thanks

 

the pics look a little blury.

 

Yup that would be from my camera phone.
Thanks for stating the obvious Leo.
I am in the process off working on my mom to get her to give me her old digital camera then Ill be able to take better photos.
