Adding “Express Down” Power Window Feature to 1992 – 1996 F-Series and Broncos

This article describes how to adapt a power window to utilize the express down feature, whereby the window goes down fully by tapping the down window switch. At the end of the article is information specific to 92-96 full-size trucks and Broncos.

A little information about the module used for this mod:

To the best of my knowledge and experience in the junkyard, these modules were only used in generation 2 Taurus/Sable vehicles. They can be found inside the driver doorskin, mounted underneath the armrest support. The Ford part number for the module is: F2DB-14B118-AB. I have heard that the dealer price for these modules is around $50, but if you grab a handful of them and tell the junkyard guy that theyre just window relays, youll get better treatment. If youre cutting it out of a junkyard car, of course you want to get as much of the harness wiring as possible.

And now for the installation information:

There are five wires coming off of the express down module. They are as follows:

1 Motor side of down wire (red)

2 Switch side of down wire (white/black)

3 – +12V (blue/black)

4 Up wire (yellow)

5 Ground (black)

If you remove the module from the harness connector, you will be able to see the numbers stamped into the plastic.

For the switch to which you want to connect the module, use a meter or test light to identify:

– keyed +12V wire

– ground wire

– the wire that goes to +12V when you press up

– the wire that goes to +12V when you press down

Here are the connections that must now be made:

Use an inline spice to connect module #3 to the keyed +12V source.

Use an inline splice to connect module #4 to the up wire

Use an inline splice to connect module #5 to the ground

Cut the down wire, leaving yourself enough room to butt splice each end. Connect module #1 to the electric motor side of this wire. Connect module #2 to the switch side of this wire.

At this point, all of the electrical connections have been made. All that is left to you is to reassemble everything and fasten the module so that it doesnt rattle.

92-96 specific information:

Since I performed this modification to a 92 Bronco, I can provide the wire colors for 92-96 trucks.

Driver door panel, driver window switch:

Down: gray/black

Up: yellow

Keyed +12V: blue/black

Passenger door panel, passenger window switch:

Down: pink/yellow

Up: yellow/red

Keyed +12V: blue/black

Ground: pink/green

Dash rear window switch:

Down: purple/blue

Up: purple/green

Keyed +12V: blue/black

Ground: black

A few more things to note about trucks of these years:

The door pockets underneath each front switch will perfectly accommodate the control module without any extra attachment; just stuff the module underneath the switch and it wont rattle. Likewise with the dash switch; it will go right behind the wires coming off of the headlight switch and stay put.

If you put a module on the passenger door passenger window switch, then either the driver or passenger door passenger switch will operate the passenger window with the express down feature.

On the Bronco, hooking the rear window module #3 wire to an always-on +12V source will not add this functionality to the tailgate key switch. An additional module would have to be mounted inside the tailgate on the circuit with the key.
