lets see some pics ! maybe how you did it too!

thanks

 

Here is how I did it. I had already drilled and tapped two 3/8 NPT holes in the intake runners before I installed my Whipple. It is highly recomended that you remove your intake to perform this task. That being said I have drilled inside of engines and intake systems on aircraft engines without removing them from the engine by drilling slowly with bearing grease packed in and around the drill bits and taps and only drilling/tapping a little bit and removing the drill bit/tap, cleaning and repeating the process many many times without causing engine damage afterwards. This process was done IAW the aircraft engine manufacturers srevice bulletin and not something a hack like myself dreamed up. How you do it is up to you and I am not responsible for any damages to your engine. I started with a 1/8" drill bit to start the hole and slowly worked my way up to the 37/64" bit. After the hole is drilled to the 37/64" you need to run a 3/8 NPT tap into the hole. I obtained my tap at a local hardware store. Once the hole is tapped you can install the IAT probe.

Heres a pic of the installed probe. I installed mine in the runner on the passenger side and just extended the wires.


I ran the wires over to the drivers side of the engine to connect them to the wires from the MAF sensor. I cut the split loom of the MAF harness back towards the main harnes and found the two wires I needed, the Grey and Grey/Red wires. Cut the wires and strip some insulation off of each wire that goes back in the main harness and solder them to your wires coming from the new IAT sensor and cover them with heat shrink. To make the install look better you can cover the new wires with split loom.

Heres my harness connections waiting to be covered with split loom.



I then started the truck up and took it for a test drive and it all worked good.

You're probably going to need to get revised tunes. By relocating the IAT to the manifold, if the tune is not adjusted for that, it's probably pulling a lot of timing due to the change in temperature between the two locations.

 

My truck actaully runs a little better now, not a lot but I do nitice a difference. I was planning on doing some data logging since I am on the rich side. I just wanted to get the correct info for the data logging instead of them just calcualting it. If that really makes a difference I'm not sure but I just wanted to do it this way.

thanks for the details

if got the parts to do mine, just need to get the time to remove the intake and do it..
