positive pulse on, positive pulse off

Hello all, I have a switch well it's actually a button that I would like to relay so that when pressed (in & out + pulse)  I will have constant 12V output, and then pulsed again, will turn it off.  It's for a rear defogger on an after market jeep hardtop. It came with a toggle but I want to use the factory switch (button).  I looked at the momentary to constant diagram but I'm not sure that's what I need since it uses a ground trigger.

Okay so now I have the switch to pulse neg. and I followed the diagram (momentary to constant ) now it works but it won't shut off until I diconect it which is I guess how the caption explains it to work, but how do I get it to shut off ? When I power it up for the first time it turns on and illuminates the led but it won't turn off.
