Just got a New Adjustabe resistor for my Rig
I just got this adjustable resistor hte MAF and the directions got lost i was wondering where to atach the red and black wires for the resistor your help woulkd be greatly appretiated thanks

Hi FA,
I don't know what " adjustable resistor hte MAF " is actually supposed to mean, so I'm not going to be able to help you get that installed.
However, if this is what I *think* it is (the typical scam where some characters are selling $0.32 cent resistors for $5-$20 to alter sensor output, saying you're going to gain power and/or performance), I'll give you some very good advice - DON'T.
Unfortunately, there are some characters claiming you can just spend $10 on a $0.32 cent resistor, and you'll gain power & performance, fuel mileage, etc., so you can save the money it would cost to actually have a proper performance program done.
And usually it's not the MAF, but instead is more often the IAT/ACT (Inlet Air Temperature, otherwise known as the Air Charge Temperature) sensor's output they're skewing - which is done to "trick" the PCM (the vehicle's powertrain computer) into thinking it's colder outside than it really is, to force it to dump in more spark advance and thus raise power a bit. This is a dumb and unsafe thing to do - not only is the amount of spark advance that will be added in going to vary widely based upon actual temperatures, but the *curve* (rate of change) in each vehicle is NOT the same. It varies widely, as do their multipliers, from one computer code to the next - even in the exact same vehicle, of the exact same model year!
You should not just go changing MAF values, or any other engine sensor's values like that.
The entire powertrain is dependent upon getting a correct and unaltered signal from the MAF meter - altering that signal is the *last* thing you want to do. The MAF is the powertrain's LOAD signal, basically - so it will affect A/F ratios, delivered timing, even automatic transmission shift points.
In short - I hope you'll do your truck a favor and not try doing any such thing to alter *any* engine sensor's output.
If you're looking for more power/performance/fuel mileage, there are much better things to do - the performance of that truck can be taken literally just as far as you want to go. But adding power & performance *safely* is going to cost a lot more than just a simple resistor.
Best of luck whatever you decide,
