I went out to the garage and took some pics of the three plugs I disconnected on my 2015. First one has a white dot on it, second one has a blue dot on it and the third one is just above the flashlight beam. Maybe this will help.

 

One question, on the last photo, I was under the impression that the plug there stayed connected and that it was attached to the block-off plate that measures exhaust temp.

Also, I really appreciate you taking the time to go out and snap a pic. I'm really trying to learn as much as I can and the forum members here have been exceptional. Much thanks.

 

No problem.

No the EGT sensor connector is a bit further back towards the cab.

 

The Last one was kinda a pain. Did you cover or protect these in some way?

 

Being in the engine compartment they should stay fairly clean but you could tape the ends and zip tie them out of the way. I've also seen people use tiny ziploc bags and tape those over the plugs.

 

And yes..... the one by the fan shroud is tough to get to. I couldn't get my hands in there and ended up using two screwdrivers.

 

Hahaha, same approach. Thanks again for the help.

 

i left them plugged in. they are shut off in the tune. dont un plug the ones on the plastic upper intake manifold, that is your map sensor, the one behind it is your exhaust back pressure sensor.

 

I unplugged them in order to avoid an potential negative consequences down the road in the instance that I have to put all the unnecessary hardware back on. I only unplugged those 3 that FX44AU suggested.

 

unplug the Brown connector to the EGR if you want to be able to return to stock ! - It only took 20 min testing to burn mine up on tune that shut it off , you will end up with EGR codes when back to stock - valve stuck open and/or p0490 and need a new EGR valve , around 200$

do what DayTrader suggests

 

that is the point of blocking exhaust gasses from entering the cooler. I think you might be talking about the guys who dont block it off, of course it will get fouled with soot. I would rather have the by pass and the valve moving than sitting dormant for years. Not to mention leaving the connectors unplugged is an invitation to corrosion.

 

It is an electrical issue - even turned off the actuator motor continued to run and burns out -

 

I unplugged the three plugs that FX showed. The last one was orange also. I pack the ends with dielectric grease. If the end is free and you have some room - like the connector has a few inches of wire on it - uou can also wrap it all up with electrical tape. I even thought about then dipping it in Plastidip to really seal it well (still removable). For the connectors that are hard to get to, I packed them with dielectric grease, then covered them with the black vinyl push-on caps to further protect them.

what is the brown connector you guys are talking about? I did the block-off with the 4 plates - do I need to be concerned about this?

 

No. Sounds like you have it covered. I ordered some thick puncture resistant small bags and I plan to put them over the plugs and zip-tie. I may do the dielectric grease as well.

 

did you get your truck all ironed out day trader?

 

Not yet. Getting the new tune loaded this weekend as I have been away. I'm hoping this remedies the situation. As far as the "hair dryer noise"...I think I'll just manage to deal with it. I'm a perfectionist...which is my downfall.

 

thanks DayTrader

 

What does the plug on the 3rd photo, by the fan, control? I unhooked the 2 on top of the egr

 

that is a butterfly valve that closes some to force exhaust to flow thru the EGR cooler.

 

Oh ok...Thanks!
