i was removing my p-28 ecu today, I notice one of the grey plug had a rip wire,seems like it was riped out of its pin in gray plug? need to know how to re-pin that wire. Its location is in middle slot grey plug 16 pin harness. black/yellow at end of plug. Also need to know what is the purpose of wire? or what does it control

 

You'll need to remove that pin...



And resolder the wire to it.

 

thanks just the info i needed
