Upgrades and Aftermarket - 99 & up 7.3L EngineUpgrading or adding OEM or aftermarket equipment to your 1999-Up Super Duty or Excursion with 7.3L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
I believe i have read that you can purchase a resistor wire to add in place of the air intake heater to prevent initializing a code. Does anyone know where one of these can be purchased. Will this also work for a system that has the glow plug module relay. I have removed the AIH, however it will store a AIH failure code i am hoping this wire will solve this. Thanks in advance.

Or you can go to Radio Shack and get a pack of 470 ohm 1/4 watt resistors for 99 cents, make your own and have extras for your buddies trucks.

It bleeds enough voltage off to make the computer think the heater is still there. It's in an AIH thread in the forums that just got archived, I can't find it now to link it for you. Do your own searches to make sure if ya like. [img]/ubbthreads/images/graemlins/wink.gif[/img]

You might consider something on the order of 1/2 or even better 1 watt. I guess you could put 4 1/4 watt in a series parallel arrangement. When I get around to my IAH delete mod, I'll probably use a 500 ohm 5 watt resistor just because I have those available to me.

At 12V and 470 ohm I=.0255319A and watts dissapated for a 12V drop is .0255319 X 12V = .306383W which is more than what a 1/4W resistor is rated at which would be .250000W [img]/ubbthreads/images/graemlins/wink.gif[/img]. I also personally like when heat is involved to if at all possible double the capicity for heat purposes since that is directly correlated to dependability and reliability.
Finally, don't forget that we're talking about heat here and dissipating it and that environment on top of the engine is a lot harsher than say in your home type electronics if they have resistors sitting in your normal 70deg home. I doubt those 1/4 RS resistors have that rating in a 200 deg ambient environment [img]/ubbthreads/images/graemlins/wink.gif[/img]

I can't believe I forgot to do the math, I used a 1/2 watt 470ohm because it was left over from a laptop interface cable I made for my buddies Turbo Buick. The thread I read it in said either would work and the heat generated at these wattages was a non factor.

You are probably right a 1/4 might work just fine and might never fail you, but that is not how I approach things ... I figure out what is needed then consider the environment and what the original part was designed for and then use the the next one or two up in ratings. One thing I didn't brother to mention is the vibration aspect which these carbon resistors are fragile when hot and can be very failure prone. I have the luxury of the wire wound resistors that I will use that many might not have that option.

Thanks to everyone for your help. Installed the resistor wire with a 470 ohm, 2watt, flameproof resistor and all codes are now a thing of the past. This is a great modification. Thanks again.

The (flameproof) resister is merely a type of resister as well as a carbon or a wire wound resister. The flameproof resistor is the more durable of the three. Once you make the resister wire you connect it from the AIH solenoid (where the AIH wire was connected)to ground.
