I installed the Radix last weekend and I have a couple of questions? I have 1 plug from the factory harness that I cant find where it plugs into. The plug is on the passenger side towards the front of the truck, Does anybody have any idea what that plug is for? Also the supplied PCV hose that connects to the PCV valve in the drivers side valve cover is not very secure, is this correct? If it is not then does anybody have any suggestions? Last question is about the hose that goes from the radiator to the throttle body & from the passenger side valve cover to the bottom of the air tube. Was I supposed to reuse the factory hoses? , I didn’t think I was going to need them so I threw them away a couple months ago while I was tearing my engine apart.

 

possibly your EVAP connector? Is it 2 pin?

 

I aready have the EVAP plugged in so that is not it, I believe this is a 4 pin plug. It is in the same loom as the 4 fuel injector plugs on the passenger side.

 

tell you what, i will look at the exploded view when i get home on "eSI", if you havent figured it out by then.

 

I just figured it out, It is the plug for the EGR which I deleted. Thanks for helping me figure it out.
