The car is a 93 4cyl, soon to be 408 conversion. I am using the stock dash wiring from the 4cyl, and I bought a v8 93 ecm and ecm harness. I am currently swapping over the dash. Here a a few pics, and I need some help with . By the way the car has no power windows or door locks.
1st pic goes behind the heater control. I found where the red and blue go, where does the yellow go?


2nd pic This plug is on the ecm harness, but does not seem to have a mate. It is kind of behind the heaterbox.
 
pic 3 is three plugs from the dash harness. They do not seem to have a mate. The square green plug, and the round grey plug from the ecm and dash harness mate up, but what are these 3 for?
And pic 4 is where the speedo cable runs through the cowl. This car was an auto and will be a stick. Will the clutch cable and the speedo cable, run through the same hole? Thanks for the help
 
the yellow goes to the defrost flap motor and look at picture for cables

back to that yellow wire. On my 90 GT parts car, I see that the yellow goes into the flap motor, however on the 93 car, the blue and red go to that motor. There is no spot for the yellow. Is the yellow a dud?, I do not remember unplugging that one. I also noticed that the blue, red, and white vacum lines all go from the controller to a plastic block, and then to their places, but there is no yellow in the block. Where does it go?
 
NewToFord I found it. It was still attached to the old dash.

Once you see it, it all makes since and why I said--- The yellow vacuum line goes to a vacuum motor cannister that's on the backside of the dash. :D
