I'm not sure how to ask this, but the zex kit is suppose to have a built in wide open sensor or something like that i was wondering how it works, i got my kit used with no instructions so i'm kind of guessing... i have a wide open switch to go on the throttle body but do i need it?

 

I believe that it's the white wire that goes to your TPS.

here you go dude:
