easy power wire

Since the wether is getting better i decide to install a "power wire" and after some hard thinking i decided to use this type of quick connection that allows me to switch resistors fast and easy, This connectors are used in Europe for audio installs and are very reliable they are available at Radio Shack.
I tested a 2.4 k ohm and a 4.7k ohm resistors using the Superchips Intake temperature monitoring feature and to know the readings are completely off at stock, at 7c degrees the readings are way higher, with the 2.4k resistor the readings are dead on 7c reeds 7c so it's staying for now for a 7 day test

easy power wire

I'm glad to see someone else fabricate their own. I did too, but I used fully insulated blade type crimp-on connectors, including on the resistors so I can swap easily. I'm using 5 watt resistors because they have way thicker wires (for mechanical strength) than the 1/4 watt. In my setup the resistors and my wiring are inside a flexible split plastic wiring cover.

OK, after 7 days of test the verdict on the 2.4 k ohm power wire is: I LOVE IT
So far i got over 1 MPG gain and the truck feels a lot more responsive, but there is a possibility that i had a bad IAT and the resistor just corrected it since it was reading incorrect without the resistor something like at a 41 degrees air temperature the reading was 55 degrees at around 40 MPH a new IAT only cost $8.00 so i might test a new one soon, but for now this setup it's a keeper

Cool! The resistors I have are 2.4k, 3.3k, and 4.7k. I hope to test all 3 this weekend.

Well, I tried out first the 2.4k resistor and then the 4.7k. My overhead display read 49 degrees F. My SC said the IAT was 10 C (50 F). With the 2.4k the SC said the IAT was 7 C (44.6 F). With the 4.7k it was 5 C (41 F). Not the 20 degrees F difference, but 9 degrees F is pretty good I suppose. I'll leave the 4.7k resistor in place for a few days and see how everything goes. My butt dyno says I may have picked up a little power at WOT.

Good idea, but probably not needed.. there is NO amperage to speak of traveling to/from IAT. Nothing wrong with the larger (higher amp rating) version, but just to clarify, if you are making your own, the smaller 1/4 amp versions will work absolutely fine as well.

Dave, do you have one mocked up with a higher value, higher than 4.7? just wondering how high we can go, before the possibility of throwing a code. This message has been edited.

Yep. I did it for no other reason than the heavier wires since my connectors are the crimp-on type. A 1/4 watt is fine.

I can stack resistors in series easily and/or put them in both IAT leads in my setup. Just connect them together. But I can't try that today. Maybe tomorrow.

How about some sort of resistor to fool the computer that the egr is still connected.........any ideas?

Just have to find out what the egr runs in resistance while running cold and hot, then get you a resistor at the same value and bypass the wiring for that!
