Default Finding IAC/IAT wires on MAF.

Ok, so I bought the x2 'performance chip' from engineperformancechip.com (I know its not a chip, only resistors), and they say for the 3/4/5/6 wire MAF's that you need to connect the module to those wires, doesnt matter which one as long as you get the correct two wires.

So I went to advancedauto and looked at the wiring diagrams for my '05 ranger, and found that the gray and red+gray wires is to something that sounded like it should be. Now, I do notice 'slight' (saying slight as in I notice a performance difference, but it could also be me just wanting it to work) difference.

I always like to double check myself and make sure its all correct, and the site had a pdf with instructions for using a multimeter to find the correct wires. Now, I do not entirely know how to use it correctly, so any input would be appreciated. But anyways, the PDF said that the wires should have a resistance (ohms) of 1000-3000. I found that the 3rd, 4th, and 5th wires - its a 6 wire MAF - (when looking at wires from air intake -> manifold direction, its only 1 direction due to air flow) have these readins (3rd with the 4th or 5th, and 4th only with 5th), but the problem is, that they are not the wires that the diagram says that goes to what I need.

So, does anyone have any idea on how to help me find the correct wires?
Also, just as a side question, does anyone know of any performance tuners available for the 2005 ford ranger 3.0l automatic? I have a problem with the engine running lean with my aftermarket intake (engine is able to breathe way too well with intake + exhuast mods). I do know that it doesnt help performance any with the intake (I doubt it doesnt when it makes the engine run lean, its getting more air faster, so possibly in combination of intake + tuner to allow the injectors pump more gas when needed will create mroe horses; whatever im learning and having fun), but I dont care, I like the looks and sounds it gives. Or if there isnt any, what are some ways to have the engine run more rich to balance out the engine running lean?

Default Re: Finding IAC/IAT wires on MAF.

The wires for the BS resistor mod are the grey and grey/red IAT wires (wire positions 1 and 6) at the MAF connector. The other 4 (positions 2, 3, 4 and 5) are for the MAF sensor and shouldn't be touched.

The GY and GY/RD are for the IAT (Intake Air Temp sensor), not the IAC (Idle Air Controller). Do not connect the resistor to the IAC which is on the throttle body, not in the MAF assembly. Better still, don't connect the resistor "chip" to anything.
