Hello all!

I’m looking for a wiring harness for my mustang but everywhere i look its discontinued!?

how can this be?

any1 know where i can find one?

will one from another year work?

flying blind here. Any help would be appreciated!!!

 

Do You Have Part Number or Number off of Tag on Harness??

Pic of Tag Would Be Great. Usually White Would Have Numbers in This Format {7r3t -12b637-ba} Example

If Not I Need a Vin You Can PM or Post!

Two Different Harnesses Plug into PCM One Has Base Number of 12b637 & The Other 14A005

The 14A005 is Part of Main Body Harness. 12b637 Is Sensor Harness.

See Connectors Pdf Which Reference Which Harness They Go To.

Finding Obsolete Parts is My Thing! I'm Retired Ford Dealer Parts Manager.

While There Are Multiple Harness Under The Hood I'm Pretty Sure You Would Be Wanting The 12b637.



See Pdf For Reference.

Something is Not Jiving in The Shop Manual, Not Unusual For The Base Part Numbers To Be Different Than Parts Side. It Should Be A 12B637 Harness Unless Number Was Changed Ford Does Love To Do That. Regardless If There is an Older Number Sometimes You Can Find Them Using a Search For Original Part Number. Pm Your Vin And I Will Run A Build Sheet on The Car Which Will Show Original Harness Number.

Your Number Supplied is a Valid Part Number For 2007-2008 Base Mustang V6 With Auto Trans. Those Are Your Only Plug & Play Options. Beware Online Sellers Who Guess What Years Really Fit! Make Sure Parts Came Off 07-08 Model! We Had Member Over At Mustang Source Recently Who Had an 06 And Used an 07 Harness on His And He Had To Change a Whole Lot of Pin Locations on The Harness To get it to Work. Not Fun!

Similar Situation With a Dash Harness Recently as Well! 07 Dash Harness in an 06! Did Not Work & Ended Up Putting Old Harness Back In!

This is What He Had To Go Through on The Engine Harness!

Still I Think There Maybe a Earlier Part Number in the Build info Which Maybe Searchable. If Nothing Turns Up Here Are Some Used Options As Far as Large Wrecking Yards Which Specialize in Mustangs
