It's under the intake horn that's bolted to the front of your turbo. It's what the air goes through thus being distributed to the intake runners and into the head

Yeah. Instead of buying a delete plug I ended up just grinding off the spring heater and capping the wire. Found out it threw a couple codes.

If it sets a CEL when deleted more than likely an emissions code, I'll see if I have a LB7 tune and open it.

Edit 2001 LB7 tune:

P0540 Intake Air Heater circuit.

2 Trips, Emissions Related.

I don't have EFI, so I couldn't delete the code. When I took my heater out I wired in a light. No codes.

I did this mod a couple months ago, the truck had efi live when I bought it and works but I only have the 5 switch no computer, do I have to buy a whole new setup to get rid of the code or how do I wire a light in there was only one wire going to the heater is that the 12v then just ground the light anywhere or what if anyone has pics or can help out that would be great tanks in advance
