This is a different type of MAF sensor that it has a burn off control circuit.

So that means this is a 5-wire sensor but not the combination MAF/IAT like in more modern vehicles.

I am attaching the wiring diagram below that shows this in more detail and it includes the wiring layout so that you can see what each color is for.

Please run through this and let us know what other questions you have. Thanks
