could it possibly be used for the rear stop lights ?

That switch should be your torque converter lock up switch, some people have used them for brake lights as well. For mine, when doing the WJ master and booster swap, I really had to mess with that switch to get it to function 100% of the time. I had to leave the bolt on the pedal a little loose and had to double nut it. Take care if using the torque converter lock up switch.

brake light switch or an adjustment problem of the same on the brake booster rod ?
thank you

How close did you get the booster rod to match the original? Pics? Did you measure it with a caliper to see if the distance from center to outside of the flat part is the same? I’ll get a picture of how I set up mine.

Thank you azzy89
I will try to loosen the brake pedal bolt, and what problem could happen if i used the white switch for the brakes lights ?

Well if something gets wired wrong you could potentially fry your TCU. But if you use it just as a switch it should work fine. Also keep in mind the brake switch is replaceable, I believe the TC switch is JY only.
