There were many vehicles using the same part. I doubt they would just deteriorate over time. They are most likely in some storage room with all the other parts we use.

don is correct!! yes a locksmith can change the new one to match your old key that matches your door locks just take him both cylinders... ign/door are the same, separate trunk key!

 btw i figured out how to remove a cylinder without a key and not destroy the column

72 RS 351 wrote: Ford has done odd things with keys over the decades. In the 80's the police cars used just one key for everything in the car, ignition, trunk, glovebox etc. I had both a 1985 and 86 Crown Vic P71 at one time, and for an emergency key at work, I had one key cut that would work in both cars, for everything in both. You just took the two car keys to a place that could make/cut a key, and have one side cut for each old key. The later Fords evidently had a weak column area around the key cylinder, a thin small screw driver could be used to force some pin on the outside surface to break, allowing the internals to be turned without a key. That was the only trick I saw when hunting for a method for my lost key 91 Lincoln. That didn't work for my car, the metal was much thicker around the cylinder.

LOL wow that's cool with cutting the keys differently on each side. I guess it would save you from pulling the cylinders out of one car to make it match the keys from the other car.

so .... I DO need to take the steering wheel off to get the key cylinder out ?

Is that correct ?

I have the ignition switch entirely removed at the moment.

The reason I question is because the drawn hole in the diagram seems to be in a different location.

yes -- I see that little push pin on the new key cylinder and can see how it pushes in only when the key is in the RUN position, but when I examine the column, there seems like no way to get to to it push that little pin in. There's like a ... cast housing around most of the cylinder it seems, probably except a little hole where .. some tool can be used to push in that pin. .. I've even kind of looked in that hole with this cool USB camera ( yes one of those 19.99 jobs from the cheapo ads .. works great for focus and light ).   I wasn't able to see the pin at all .. I can't really tell what I'm looking at, but it doesn't look like that pin.

I would love to not have to take off the steering wheel. It looks like a couple of the hex heads that hold it on are a bit stripped.

no the place to push the pin in is inside under the turn signal switch

Well done, those details and the electrical stuff is great to get finished right.

I think I am missing some other harness.   If you please :

I have the light for the ash tray. Have a look at the connector. I don't seem to have the other side of the connector attached to the harness in the car :



I have the glove box switch. ( Can someone send me a picture of where / how this switch is mounted ? I can't seem to figure it out ) Again here I don't have the other single barrel connectors which connect to these individually :



Currently on the car's harness I have this 4 pin connection, which seem to have the appropriate colored wires. The brown wire which carries the constant 12v when the headlight switch is pulled out in either position (parking lights or headlights), the black ( constant ground ), the light green wires with yellow stripes(2 of them), which carry constant 12v all the time, and then the light blue with red stripe wire which carries 12v also when the headlight switch is pulled out. ( I forget why it's different than the brown wire right now ).


(I'm also not sure about that little single pin connector on the left with the black with light blue stripe )

but it seems like I am missing this harness 15A856 ( I think that's the one according my schematic )

Can anyone show a picture of this harness or does someone have one ?

I think that's the next thing I'm missing.

you need 1 of the 14 pin main connector flat pins??? i have the harness that i cut the other connector from... its good but has a rusted fuse box  i can remove 1 from it...
 IIRC the glove box switch is in the top area by the glove box rubber bumpers... the light is in the left side of the liner if i remember right?
