What GEM module

[kenman]

Bought a 99 ranger 3.0 flex, was auto trans changed to 5 speed and manual t.case. was in a shed last 10 year's. Nice truck. But no GEM MODULE. No old one, was removed. No part # to refrence. Base truck. How do I find out what GEM module is needed. This is a very clean truck. The person who owned this passed away 9 year's ago, so can't ask them any questions. Any ideas, Thanks

Welcome to TRS

GEM module runs the cab electrics, like wipers and dome lights, power windows and door locks, also was 4x4 controller and speedometer interface in 1998-2000 Rangers

Engine model, flex/gas only, manual/auto doesn't matter

For 4x4 use XL5T-14B205-EA(or EB), these all came with keyless entry

Thanks Ron
That's a part # I needed. In the spare parts I got with this, was 3 GEM' s none installed so just got to see what the numbers are.

A 1999 Ranger would not have come from the Factory with a Manual Transfer case, so previous owner would have swapped that in

So you may be able to use a 2WD GEM if push comes to shove, but has to be 1998-2000 GEM to have the speedometer interface, only years that was used on Rangers


GEM is the "body computer"(BCM) Ford's part number for that in ANY vehicle is 14B205 the center number on a Ford part number
The numbers before it are year and vehicle model its for, i.e. XL5T
Ford changed year and model designation in 1999
F7 = 1997
F8 = 1998
X = 1999
Y = 2000
1 = 2001
ect

7 = Ranger/B-series, pre-1999, i.e. F87 = 1998 Ranger part
L5 = Ranger/B-series, 1999 and up, i.e. XL5 = 1999 Ranger part
4th digit is the Department at Ford responsible for the part, so not related to fitment

The numbers after the part number are Revisions, AA, AB, AC ect........
But in the case of "computers" its also a software version, so a 2WD GEM would have different revision/software number than a 4WD GEM

This applies to all Ford part numbers (year/model)-(part)-(revision)
