So I got the ntk sensor and as u can see in the pics , one of the "square slots" is off set unlike the original one , also on the original contecter is written 3n but on the ntk connector it says 6n . The ntk will not fit onto the male connection on the truck. I will return it but I don't know which one to order as the ntk sensors don't show a pic of the female connector on the rock auto website. There is a denso that has a pic that looks right but oem for my truck is ntk
