Brake lights need help real fast

[BadBoy]

Hello i need help fast my 1992 ford explorer brake lights only come on when the ignition is turned on then they will come on when i press the brakes if the ignition is off they will not come on i check all the fuse and they are good.
Is this normal i need to know fast for i am hooking a alarm and need to hook a wire so when the brakes are pressed the engine turns off when i remote start the explorer

Thanks

I'm not sure what you're saying because you didn't use any punctuation, but there is a switch at the brake pedal that you need to tap into. I think the wire is blue, but I can't remember. You probably have the color among your paperwork. You just splice the brake switch wire from your computer of your alarm into the wire at the brake pedal.

There is a schematic of the body wiring here:

Look at Fig 14 for a 92 Explorer. The brake light switch should be supplied by Fuse #4 in the inside fuse box. You should try to determine whether this fuse is hot all of the time or just when the key is on.

It should be hot all of the time, the brake lights should be on when you step on the brake whether the key is on or not.

Thanks I have to look at the whole fuse box.
I looked and right now there is a wire that comes from the front by the battery and is on a relay.When i turn the explorer on then that wir has power and the brake light's will work.I try unpluging the wire and then turn the explorer on and the light dont come on.

Also i looked at auto zone but i cant get fig14 to go large so i cant see the wire's.

Thanks

Just run a wire from an always on 12v to the realy or fuse of your brake light's supply. Then they'll always be on, that is if everything else fails.
