new MILS and o2 install q's

CLIFF NOTES AT THE END!!!

So i live in the city now and have no use for my car and its hefty insurance payment here, so i left it at my parents house about 20 miles away and havent driven it since new years. Anyways... the AC went in my mom's minivan and instead of fixing it, she decided to just get a new car. But until then she thought it would be cool if she could just use my car since im not using it. So being a good son, and appreciating the fact that i have been parking it there for free in their way for like 6 months... i agreed. Problem is, im uninspected do to the longtubes and off road prochamber. So i bought MILS and o2 extenders from mustang tuning, now all i need to know is where do i run the extenders too?? Once my check engine light is off, a buddy of mine said he can get me a sticker on the low.

Cliff notes: how and where do i install the o2 extenders??
