I ordered up a replacement turn signal switch to replace the one going out in my truck and finally got around to replacing it last night after having someone else's order shipped to me by mistake (another long story).

I tore apart the steering column, swapped in the new switch, and buttoned everything back up, only to find out I had NO turn signals OR brake lights!

I pulled everything back apart and found out that although the plugs on the old and new switch are the same, the pin-outs are different. So now the old part is back in while I wait to get the right part shipped to me. I just hope the old switch hangs in there for another week or so...

The part I ordered that didn't work was F89Z-13K359-AB. The part I pulled out of the truck is F3TA-13K359-DA. Does anyone know if this is the part number used across all of our OBS 7.3s?

Thanks!

 

I dont know, but maybe this is the motorcraft part num: Motorcraft SW5581 but dont quote in that.
