No.. both motors use the same firing order.

 

Ok cool. Ill update as i make progress.

 

Ok so i still havent had time to get the rest of the parts for the MAF swap yet....mainly cause by the time i wake up the junk yards are closed but ive put almost 10,000 miles on the truck in the 2 months ive had it and last weekend i was creeping around the pasture and it started knocking....It kept knocking all the way back to the house but then that night i went to town and it wasnt knocking anymore......well next day it it started knocking again and then just quit knocking and hasnt knocked anymore since.......Never had one knock then quit....But im not gonna complain but i am fixing to have it rebuilt this weekend so that brings me to the next question....

Since its gonna be apart id like to do the GT40 head swap and wanna know exactly what years explorer will work and whether to get 3bar or 4bar heads and also if the gt40 valve train is worth keeping. Im hoping to get a pair of long tubes shortly after and will be running true duels with an H pipe and will exit in front of each rear tire

 

Ok finally made it back to the junkyard and got the MAF computer but they had done cut most of the harness out of the truck. Can anyone walk me through the process of redoing my harness to work with MAF?

 

First thing you may want to determine is exactly which MAF ECM you have. Can you post up a pic of the label? If not, can you post the exact and complete part #s from the label? Also check the connector pins. 60 pin or 104 pin connector?

Not sure if those are O's or zeros they all have a line going through them

HUG0
GSKT NPF 3H193
*CDSK929GJN30*
SMD-219
F4TF-12A650-APA

60 pin

 

Well, that's a good start. There are OBDII MAF ECM's out there as well in the 104 pin package. That would have made things extremely difficult.

I think most of the changes include adding the MAF sensor wiring, deleting the MAP sensor wiring and replacing the bank fire injector wiring with the sequential injector wiring. There may be more and I am sure Conanski would be the expert here.

A couple resources you will need include EVTM's for both MAF and SD versions of your truck. The 5.0 MAF diagram will work just fine. There may be some online versions, but having the factory document on hand is always helpful.

Another great resource were the old RJM sites. Fortunately some archives still exist.

Happy reading!

 

Thx for the info bud and yeah i was hoping Conanski would chime in again also
