Solenoid wiring
 

Hello fellow boaters, I have a solenoid that went bad. I replaced it and I can't find the picture of the old one before I took it off. Need a little help with what wire goes where? Not sure how to add pic off my phone? Might need to have a free post under my belt before I can add any pics.
So, I have a red wire and yellow wire with a washer type connection that would be secured by a nut. I have a black wire and a yellow wire with a female end that slips onto a terminal. Thanks for your help.

This is what I figured out. The red & Yellow wire does not matter which stud it goes to and the black & Yellow wire does not matter which stud it connects to. Unless I got luck on which wire goes where.
