Where is the Back-up light switch is located?

Post by Dumindu » Tue Apr 09, 2019 6:26 pm

My car is a Toyota Tercel 1987 4WD 1452CC DX Wagon.

Yet my car Back-up light is not working with reverse gear. Earlier connection wires couldnt find and I could find it with your guides.

I connected the found wires to a wire hanging from the gear box but that wire was a ground wire. Now I am using a manual switch installed near the gear shift lever to light-up the back-up light.

As I found in the service manual that proper switch should located on the right aspect of the gear box. But I cant see any switch or a hole for the switch in my gear box.

If anyone knows the exact location of the switch please advice me (better if I can get a real photo) so I will able to at least find the hole for the switch (If it has been removed) to install a new one.

Is that picture of the bottom view of the gear box or top view of the gear box?

that is the top view. It would be hard to see from the bottom, use a light and look up over the left side, it looks like an oil change plug with a wire coming out of it.

I have never heard of the switch itself going out, usually it is a worn or chaffed wire (gets cut from rubbing against frame or other hard part). Often if someone removed the transmission for other service (like a clutch, or replacing the rear main seal), they will forget to connect up the wires again, or perhaps they damaged the wires removing the trans (that is fairly common when someone forgets to disconnect the wires from the trans).

If the wires are all okay, and you have confirmed the wires are not damaged, it would be easier to remove the switch by lowering the back of the trans by unbolting the rear cross member and let the rear come down several inches. you should not have to remove anything else just to lower the trans, and it will make access easier if necessary.

good luck.
