Wiring diagrams

Ive got a 2004 ford explorer xlt with the 4.0 v6. I had a couple codes pop up and im trying to figure out the issue. I wanna rule out the maf sensor and the egr/map sensor out. So i need the wiring diagram to figure out what wire is what so i can test it with a voltmeter and see if everything is working properly. Ive looked every where i could think of. I dont have a haynes manual but i do have the owners manual but that didnt tell me anything.

What did you find?
I’m in a similar situation. Just want to be sure all engine harness wiring, especially to sensors isn’t compromised in some way. I’ve looked online and have yet to find a print

No one ever got to me either but i ended up finding a good cheap part off carparts.com for the maf sensor and went ahead and replaced it. Fixed all the issues i was having. Car runs great now
