My EF Fairmont has an ECU with 94DA-12A650-CC on it and it has failed in the idle speed control section.

I've been offered one which has 96DA 12A650 BB on it, but I don't know if it is really compatible.

Does anyone know how to find out?

and what should a second hand one cost?

Also I figured out that the bit that failed is called a 71007SB. Where do you go for one of those?

It seems to be suitable just going from the part numbers? But then.... I have no idea.

generally el ecus had 96da part numbers.
el ecus have totally different plugs and are not compatible.
you need to find an ef ecu which will have a 94da part no. you can get them on ebay for like $40.

hope this helps

Also be sure the Idle speed motor is replaced or checked out to prevent another dead transistor on the ecu.
