Header, Intake, & Exhaust - O2 sensor simulator question

I got one of these things so I could use my straight pipe when I go do emissions. Has any one installed one of these things? The instructions say that there should be 2 white wires, a grey and a black and to cut the grey and black wires and splice the simulator in. My problem is that I have 2 black wires and a white and a green. So does anyone remember which wires you cut and spliced with the simulator? Thanks!

Where did you get it from and are you sure you got it for your obd?

I got it all straightened out. Check my other post.
