I AM SWAPPING IN AN AOD AND THE AOD'S WIRING HARNESS HAS 6 WIRES AND THE T6 HAD 8. THE CAR SIDE HAS 8 AS WELL. I HAVE THE T5 HARNESS STILL AND NEED ASSISTANCE ON WHICH WIRES I NEED TO SPLICE INTO THE AOD HARNESS AND WHERE AND WHAT TO DO WITH THE 2 EXTRA WIRES. ANY HELP APPRECIATED
SORRY T5. 1988 5.0 AOD. WIRES ON AOD AND T5 ARE SAME COLORS EXCEPT T5 HAS A LT BLUE/YELLOW WIRE AND A BLACK/WHITE WIRE EXTRA. JUST NEED TO KNOW IF THESE 2 NEED TIED TOGETHER OR JUST LEFT OUT
The balck/white wire is the nuetral gear switch for the T5 and it goes to a contact on the top of the transmission cover plate. There is a tapped hole there that gets a small actuator rod down the middle and a switch that gets screwed in behind the actuator. This is used by the EEC to sense the trans is in nuetral so that you can pull codes from the EEC. If you don't have it, you don't get codes but the car will run. The other wire is probably the wire that feeds the backup lights and it's switch is on the passenger side of the transmission about half way down.
