You put the resistor on the output of the AIH to ground. It's the one with the blue wire attached. I spliced some resistors into the ground wire that is disconnected during AIH delete and connected it to the output of the aih. Below is a pic of the setup I used. It's the same as a 470 2 watt resistor. I got them at radio shack. I used some heat shrink over the resistor/wire.
I think on most trucks it only sets a soft code and no CEL. Did you scan it after?

I actually mutilated my AIH by removing the part that stuck into the plenum... I finally decided to get a plug for it last weekend. Its just a Cummins oil pan drain plug, but the Riffraff piece is prettier and already tapped for boost, etc!

The AIH allegedly occupies about 20% of the space its poking into. So, some restriction seems logical. AIH is very, very rarely activated and likely wouldn't be missed if it was called for and not there - this is my many of us have chosen to 'delete' it.

My thinking is, I don't think it is a restriction for air. On a gas engine, air is being sucked into the engine, but with our turbo engines, the air is forced into the engine. I can see where the AIH would be a restriction with a gas engine. The MAP/boost line is after the AIH and my boost is close to 40 psi.

AIH delete is a perfect example. Even though nobody has ever documented a dyno gain from this mod, it was one of the first things I did to my truck. Why? IT WAS FREE!! I felt better 'cause it seemed like a good idea and there was certainly no noticeable NEGATIVE effect, soooo why not??
Zoodad is another example - unfortunately, it DOES have a very negative effect. The air filter gets dirtier MUCH faster than without it. Again, nobody can document there is a benefit from this mod but many of us did it as a first mod - because it is FREE (and it sounds like a good idea).
Oh, FWIW my Excursion is ALL stock, except for AIS and chip (and BTS trans!!) and it makes almost 30psi - with a stock muffler!
There are others I try to refrain from mentioning, because my flame suit got burned up a loooong time ago. The more time, effort and money people spend on a 'mod' - the more feverishly they defend it!

Well put Rick. There are waaaay too many 'common mods' that have no measurable benefit whatsoever. We just can't seem to help ourselves - especially if somebody sez its a good idea and 'everybody else does it'.

I agree Jason. Heck, I never did and will not do the CCV mod. Didn't we put your CCV back to stock when you came here? I think having the CCV going into the cylinders makes my truck faster.
