Hey guys i'm new here and im sure its been discussed a billion times but anyway iv got a 1989 f150 xlt lariat 4x4 with a 5.0 efi and e40d transmission. Im just lookin for a list of everything i will need to do a MAF im plannin on goin to a junk yard and pulling all these parts. Thanks!

 

Please help!!! I need a list of these parts asap!

 

You need a MAF computer and meter from a 5.0/E4OD truck and while you're in there grab the air box cover and Y pipe, and then you need a complete(all the way back to the computer) engine wiring harness for a MAF truck motor. That will not simply unplug you're gonna have to cut some wires to get it out, but that doesn't matter because you're not gonna use it all anyway, you're gonna strip all the tape and wire loom off it and remove the injector and MAF meter sub wiring assemblies and create a little overlay harness to put on your truck. To do that you have to disassemble the computer connector on your truck, remove the pins for the stock injector harness, and insert the pins for all the wires in your overlay harness. Got all that?

 

Thanks! Thats alot more than i expected but i think i got it! One last thing what uear donor truck am i lookin to get this out of?

 

They are tough to find.

I'd suggest getting an aftermarket, layover conversion harness and order the proper computer/EECIV.

I've got a MAF meter, "Y" adapter, single intake hose, and air box for the conversion. PM me if you are interested.
