Replacing a backup light switch is fairly straightforward if you know what the switch looks like and where to locate it on your vehicle. A backup light switch screws into the transmission and is triggered when you shift the vehicle into reverse. If the switch is functioning normally, a circuit is completed when the switch is triggered and the white lights in the tail lights will illuminate, indicating to other drivers that you are backing up.
It is important to rule out the most common problem, which is a burnt out light bulb. This article is written with the assumption that you have already checked for burnt out light bulbs. By following this how-to, you should be able to successfully identify and replace your backup light switch.
Step 1: Remove the battery. Use the box end wrench to disconnect the terminals connected to the battery. Once the terminals are removed, use a socket wrench to remove the battery hold down bracket if there is one. This bracket will be secured with two bolts or nuts.
These nuts or bolts are commonly sized 10mm. Step 2: Remove the battery tray. Use the socket wrench to remove the nuts or bolts holding down the battery tray and remove the tray.
Step 3: Remove the air filter box. There is either a squeeze-type clamp or a screw-type clamp holding the intake pipe to the filter box. Step 4: Attempt to locate the backup light switch on the top side of the transmission. On some vehicles, the switch may be visible at this point. If you have a transverse sideways mounted engine, you should be looking at the top side of your transmission. Examine the electrical connector on the new switch and look for a sensor plugged into the transmission with the same amount of wires coming out of it, and a similar looking electrical connector.
If you find the sensor and can access it from above, skip to Part 2. Step 5: Attempt to locate the backup light switch on the bottom side of the transmission. Jack up the front end of the vehicle and secure the vehicle with jack stands. Typically a splashguard will need to be removed if the vehicle has a transverse mounted engine. It is common to find 10mm bolts or Phillips head bolts retaining the splashguard.
How to Replace a Backup Light Switch
Remove it to expose the bottom of the transmission. At this point you should be able to locate the sensor on the transmission. Step 1: Disconnect the electrical connector. Squeeze the tab on one side of the connector and disconnect the switch from the wiring harness. Sometimes there is a retainer clip holding the wire to a nearby bracket to keep it secured and out of the way. Gently remove any retainer clips found. Step 2: Use an open ended wrench to loosen the switch.
When the switch is removed, replace it with the new switch and carefully tighten the switch back into the transmission. Tighten it firmly but do not use excessive force as the transmission case is usually aluminum and you do not want to strip the threads. Step 3: Reconnect the switch to the wiring harness. Once the electrical connector is plugged back in, make sure to replace any retaining clips you may have removed in previous steps. Step 4: Reinstall the disconnected parts.Skip to main content.

Atomic Industries www. Register now to get rid of these ads! The H. I have a T5 installed in my 51 Chevy. It still has the reverse light switch in the side of the housing but I have never hooked it up. My Rebel 21 has a circuit for back up lights that I have pulled the wire to the rear of the car but I don't know how to wire the switch to the lights.
In all of the searches I've done it shows a pigtail inside to a column plug but I have the stock column so no wires.
Wiring up reverse/neutral safety switches on a T5?
Can anyone guide me on how to wire this up so I can get some back up lights? I'm planning on mounting some lights under the rear splash pan so they are hidden but still throw light when needed. Thanks for the help.
Of course, don't forget to ground the lights. Since your switch wiring is located by the column, I would just mount a relay there and run a single wire down to the transmission. If your reverse switch is a single terminal, it should ground when in reverse, if it has two terminal, just ground one of them by the switch.
This is what I have. I believe the plug on the lower part of the trans case is the reverse lights switch. Johnny GeeJan 7, Looks like I don't have the neutral safety switch. Johnny GeeJan 8, Forums New posts Search forums.
