14A624 is related to the power windows of a '86 Taurus (E6DB), the processor (computer) is basic ID & part number 12A650.

There are no application charts, if one doesn't have the correct ID number marked on the processor, one has to troll thru the Calibration Code parts lists to find the correct part number.

1988 F250 460 4WD M/T: 7-97A-R01 ~ 7-97A-R10 ~ 8-97A-R0 are the three Calibration Codes that apply.

Pic: One of the nine pages of processor ID numbers to Ford part numbers. Where is 14A624? No see um.

Notice the ID number marked on the processor is listed first, followed by the part number.

 

The truck in question is; 1988, 7.5L, EFI, F250, Manual Tranny. 4x4


RF-E7TE-9425-BB; this is the only other number he found on the exhaust manifold.

All his stickers/Cal code etc have been painted over.

 

Calibration Code 7-97A-R01 (parts list #644) & 7-97A-R10 (parts list #647):

E7PZ-12A650-DA .. Processor Assy / Marked: E7TF-12A650-BT1C or BT1D or BT2C or BT2D
------------------------------------------------------------------------------------------------------------
Calibration Code 8-97A-R0 (parts list #666):

E8TZ-12A650-BLB .. Processor Assy / Marked: E8TF-12A650-BL1B or BL2B

Look on the B pillar below the striker plate, or on the valve cover, or at the top center of the radiator support for the sticker that has the Calibration Code printed on it.

Post what it is.

 

Numbers on the breadboard are E8TF-14A608-DE and I cannot find any calibration code, I'll look again tomorrow just in case

 

This number is not related to the processor, as it has a basic number of 12A650

 

Thanks Bill, looks like it is whether there are 3 or 2 vacuum solenoids/1 or 2 Thermactors.
