IAT / ECT Sensors

[SRMobile]

IAT = Intake Air Temp
ECT = Engine coolant temp


For you tech guys, I need to know what the color of the wires for each of these going into the computer.

I had done a potentiometer mod in my previous car and there was a significant gain. It was the best bang for buck mod I have ever done and on a 4 cyl Zetec (yayaya dont laugh) it bumped the peak HP by 5.4 and the TQ by 7.7. I figure on this huge engine(previous was 122 haha) there will be more to gain and I still have my previous setup.. All I have to do is splice in and give it a try.

thanks in adance,

sorry im not sure of the color wires but im curious to know what this mod is

Basicaly it takes advantage of the emisions system. Ever notice how your car has abit more balls on colder mornings? Its due to the fact that your car is programed to warm up to normal temps,for cleaner emissions.

To do this, it advances timming and dumps in more fuel. Hence the more balls.

more balls is good...

any writeups on this? how hardis it? sorry to steal ur thread man but im curious.

Well this is the thing, it doesent look like anyone in the Stang community has attempted this mod... There are write ups, but its for my previous car(Zx2 S/R). I know this will work because we had guys who did it to Windstars, Rangers and F-150's.. So I dont see why it wouldnt work on the stang. Thats why I need to know the colors of the wires so I can tap in and try it out, then I'll do a write up.

IAT:
Gray/red stripe and Gray

ECT:
Gray/red stripe and Light Green/red stripe

Note that the same gray/red wire connects to both sensors.

n0v8or, Thanks for the info!

Just want to confirm that this was on a 2003 ?

What source did you get this from ? It might help me out abit more to understand the GREY/RED stripe wire...

I'll bet that I just need to tap the other two and leave it out..

Thanks again man!

 

[RysRed96GT]

let us know what happens when u did it and how hard it was

 

[n0v8or]

I have the 2003 factory wiring manual.
I'll scan and post the drawings for you later tonight.

Note that the IAT is built into the Mass Airflow sensor.

any updates on this? did u get it working yet?

Thanks for your help n0v8or!

I'm comparing the diagrams with my old vehicle and should have this up and running by the end of the week. My car has to go in for the Tremec TSB and my SES light is on cuz my gas gauge is all screwed up, so when I get my car back I'll be able to go a head and tap those wires. I'll keep you guys updated no worries!!
