if you wanna spend the money for it. mine is free (other than the maybe two feet of wire)

A bunch of us had a cruise yesterday,so i paid attention to see what you were talking about,and your right!!....looks weird.
How did you get the two 3rd lights to come on with the other's?...in detail to please.....:biggrin:
I'm sure i can figure it out,but since you did it,it's easier for you to share the info. :wink:

The 99+ Mustangs have six tail lights, but when you hit the brakes only the outer four lights come on. It is easy to modify the left and right tailight modules so that all six light up when the brakes are applied. The inner sidelamp sockets are already set up for dual filament bulbs. They just lack a wire to supply power to the second (brake light) filament.
The following instructions and the four small photos come from an article by David Roe [see his web page]. Thanks David. I contributed the animation above and the the large annotated photo at the bottom of this page.

You need to scavage a few parts from a late model Ford tailight socket. I suggest you pick up a used socket at a junkyard. New ones can cost as much as $35 (Ford P/N F7ZZ-13411-AB). Take the socket apart by prying the cylindrical collar from the rear cap (it's just a force fit.) Then remove two wires with pins at one end, as shown above. These wires will be used to modify the inner sidelamp sockets in the left and right tailight modules.

Remove the trunk liner to get at the four nuts holding the tailinght assemblies on the car. When those nuts are removed you can unplug the wiring harness, push the rubber pass-through grommet out toward the rear, and remove the tailight assemblies from the car.

Remove the sidelamp socket (shown above) from each assembly. Notice that it has two stock wires with pins already in place. You are going to insert one of the wires you scrounged in step 1 (also shown) to make a connection to the second filament in this socket.

Take the new wire and push its pin into the hole provided so that it makes contact with the unused electrical tab.

Use a razor blade to make a slot in the rubber strain relief plug for the new wire. Then push the stain relief plug into place.

Reinstall the cylindrical collar, the white rubber gasket, and the original 2-filament bulb. Then reinstall the sidelamp socket into the tailight assembly.

Splice/solder the new wire to one of the existing green/red brake leads coming out of the other brake socket at a terminal marked "MAJOR", as shown below.

crap.. photos dont work.. but here's basically all you need for pics.
for those of you that worry... the other bulb is a dual bulb like the others so no relay/fuses are needed

Cool,thanks.
Is there anyway to get all the picks up?
Save them to your pics folder,then host them to where you normally host them so we can see them. :biggrin:
Then i will print this screen,and save it. :tup

yea not a problem. been at the cabin all weekend so i'll try to get on it tonight

No prob's,and thanks!! :wink:

you try this yet? i just got my cobra tails on and omg is it a sweet combo :tup

No,i haven't had time to try it.It might end up my winter project.

ok. i have a bunch of sockets with pins (even though you really only need two extra pins) that i can send your way if needed. or anyone else interested.
