Hello people I just got a 03 mustang base v6 engine and I missing the mass air flow sensor harnnes conector like I show in the picture but I can't find one I don't know why is to hard if anybody knows where I can find one I appreciate thanks
I just brought the car on a auction and is my first mustang , I have check engine code p0113 which is someting with the mass air flow sensor , the complete sensor was missing so I bought one and like I said the connection is missing too
Ok, so with that context, I went a huntin'. That plug is for a secondary harness, Ford Part Number: 1R3Z-12B566-AA. It runs from that plug to two, not one, sensor: The MAF and the Air Charge Temperature sensor. So you'll need that harness, a MAF and a ACT, plug them all in, and done.
Problem is, that harness is discontinued. So your likely only hopes are to either find a 3.8L at the junkyard and scavenge the harness that way, or get *really* lucky. That, or get a Ford wiring diagram and direct-splice the connectors needed for the MAF and the air temp sensors that the harness is for. The air temp should be under the airbox. Ford sells all those connectors, so maybe hit up a Ford dealer and see if you can get them to look it up and get 'em for ya.
Don't be fooled by other -12B566- harnesses you might see. It should be only this one. There are others you might find that're for a Lightning or a Mustang GT, and I'm thinking (but don't actually know) they won't work for you here.
And I see them two blue scotchlocks. Makes me wonder if the harness still has good integrity overall... good luck, man. Hope this gets you closer.
